Answers

Answer 1
Answer:

Answer:  The required cost of 0.7 pounds of sliced meat is $7.35.

Step-by-step explanation:  Given that Marcus can buy 0.3 pound of sliced meat from a deli for $3.15.

We are to find the cost of 0.7 pound of sliced meat.

We will be using the UNITARY method to solve the problem.

We have

the cost of 0.3 pound of sliced meat = $3.15.

So, the cost of 1 pound of sliced meat will be

(3.15)/(0.3)=(31.5)/(3)=\$10.5.

Therefore, the cost of 0.7 pound of sliced meat is

10.5*0.7=1.05*7=\$7.35.

Thus, the required cost of 0.7 pounds of sliced meat is $7.35.
Answer 2
Answer: $22.05 because $3.15 times 0.7 is= 22.05

Suppose you earn $6 per hour at your part time job what will your new rate be after a 2.5% raise

Answers


2.5% means 0.025 .
After an increase of 2.5%, the new rate is (1.025) x (the old rate).

1.025 x $6.00  =  $6.15 per hour.

If you work a full 40 hours in some week, you will be blessed with
a full $6 more for the week of toil than you would have collected
at the old rate.

You were not overpaid before the raise, and you must not allow
your boss to act as if you should kiss his ring or prostrate yourself
before him in return for 2.5% .  It was not too long ago that 2.5% was
tantamount to being shown the way to the door, and a tacit suggestion
that you consider following in the way of the arrow.

His profit from mowing x lawns is p(x) = (r- c)(X). What is p(x)?
A. p(x) = 31x+15
B. p(x) = 19x - 15
C. p(x) = 19x+ 15
O D. p(x) = 31x- 15
SUBMIT

Answers

Answer:

His profit from mowing x lawns is 19x-15

Step-by-step explanation:

Revenue for mowing x lawns = 25x

Cost for gas and the mower rental = 6x+15

We are supposed to find His profit from mowing x lawns

p(x) denotes His profit from mowing x lawns

Profit = Revenue - Cost

So,p(x)=25x-(6x+15)

p(x)=25x-6x-15

p(x)=19x-15

So, Option B is true

Hence His profit from mowing x lawns is 19x-15

Identify describe and extend each pattern 64,55,46,37,28,19

you subtract 9 each time. 10, 1, -8, -17, -26
You are subtracting 9 each time, or, if you are a visual learner, an easier way to understand it could be that the left digit always goes down 1 and the right digit goes up 1. So because of the found pattern, the next numbers would be 10...1...-8...-17...-26...-35...-44...-53... And so on. Something to remember is that when you start getting into the negative numbers, the visual pattern goes vice versa. The left number goes up 1, and the right number goes down 1, when there are negative numbers. Whereas for positive numbers, left goes down 1, and right goes up 1.
