this is not part of the problem but im sorry if this is to easy but i need some help with it because my english is not that good so i don't get it....

Answers

30 x 0.05 = 1.5

30 - 1.5 = 28.5

28.5 + 1.5 = 30

$30 is the final answer

From what I understand if the discount would be 5% and then there is sales tax you would be charge that 5% so there for you would not get a deal off the item you are buying it would stay the same price. So the final price is $30.00.

Mrs Larnell is making a snack packs for a a class picnic. She puts 1/4 pound of apples,1/8 pound of nut mix, and 1/16 pound of chocolate in each of the students packs. There are 24 students in the class.What is the total weight of the snack packs? Is there more than one way to solve this problem?

Answers

Answer=10 1/2 pounds

One pack has 1/4+1/8+1/16 pounds of snacks....

Lets starts off giving our fractions of 1/4, 1/8 and 1/16 a common denominator of 16.

1/4=4/16
1/8=2/16
1/16=1/16

So...

x=4/16+2/16+1/16
x=7/16

So... One pack has 7/16lbs of snacks in it

Multiply 7/16lbs by the total number of students(24)..

7/16*24=10 1/2 pounds
________________________________________________________
another way of solving this problem could be...

1/4*24=6
1/8*24=3
1/16*24=1.5

6+3+1.5=10.5 pounds
