You have $75.00 to spend at the mall. You want to buy a hoodie that costs $80.00. The store is having a 20%-off sale. (There is no tax on clothing.) Can you buy the hoodie? If so, how much money will you have left?

Answers

Answer 1

Answer: ok so find 20% off and see if less tha 75
percent means parts out of 100
20% means 20/100=1/5

'of' means multiply

20% of 80=1/5 times 80=16

off means subtract
disctoun tof 16 is 80-16=64
64<75

how much left over
75-spent=left over
75-64=11

anwwer is $11 left over and enough money to buy

Answer 2

Answer: hey there i see you need help so i am here to do just that you CAN buy the hoodie because 20% of 80.00 is 16 so you subtract 16 from 80.00 and get 64

A drawer has some red, green, and blue marbles. There are 33 marbles.There are 4 times as many red marbles as green marbles. There are half
as many blue marbles as green marbles. How many blue marbles are in
the drawer?

Answers

Green marbles = x.
There are 4 times as many red marbles as green marbles, so red marbles = 4x.
There are half as many blue marbles as green marbles, so blue marbles = 0.5x
There are 33 marbles in total, so x+4x+0.5x=33.

$x+4x+0.5x=33 \n 5.5x=33 \n x=(33)/(5.5)=(330)/(55)=(30 * 11)/(5 * 11)=(30)/(5)=6 \n \n0.5x=0.5 * 6=3$

There are 3 blue marbles.

so number of red is represented by r
number of green is represented by g
number of blue is represented by b

so r+g+b=33

there are 4 times as many red as green or
r=4g
there are half as many blue as green
1/2g=b or g=2b

so r+g+b=33
we can subsitute 1/2g=b for b
r+g+1/2g=33
subsitute r=4g for r in the equation
4g+g+1/2g=33
add like terms
5 1/2g=33
multiply both sides by 2
11g=66
divide both sides by 11
g=6

there are 6 green marbles

subsitute g=6 into r=4g and g=2b

r=4(6)
r=24
there are 24 red marbles

g=2b
6=2b
divide both sides by 2
3=b
threre are 3 blue marbles

there are 24 red marbles, 6 green marbles, and 3 blue marbles and 24+6+3=33
r=24
g=6
b=3

A chef makes 13 gallons of soup in a largepot. How many 1-cup servings can thechef get from this large pot of soup?

Answers

1 gallon = 16 cups

The picture that was attached to this question talked about 1 1/2 gallons. So assuming that you need to solve for how many cups are there is 1 1/2 gallons you need to do:

We know that 1 gallon = 16 cups, so 1 1/2 (or 3/2) gallons would equal to: $(3)/(2) * 16$ , which would equal to 24 cups.

Step-by-step explanation:

A northbound bus and a southbound bus are at a bus stop at the same time. The northbound bus returns to the bus stop every 20 minutes and the southbound bus returns to the bus stop every 25 minutes. How long will it be before both busses are at the bus stop at the same time again?

Answers

Answer: It will be after 100 minutes both buses stop at the same time again.

Step-by-step explanation:

Since we have given that

Number of minutes after which the northbound bus stops = 20 minutes

Number of minutes after which the southbound bus stops = 25 minutes

We need to find the number of minutes it will before both buses are at the bus stop at the same time again.

So, L.C.M. of 20 and 25 = 100

Hence, it will be after 100 minutes both buses stop at the same time again.

5 stops for the north 4 stops for the south
