Question

erin is making lemonade. she needs 1 1/4 cups of white sugar to make 8 cups of lemonade. she has a 32 cup pitcher to fill. how many cups od sugar will she need

Answer 1

x = (1+3/4)(32/8) = (7/4)(4) = 7

Explanation:

Given that Erin needs (1+3/4) cups of white sugar to make 8 cups of lemonade, then the number of cups of sugar she will need to fill a 32cup pitcher is (x represents the number of cups of sugar ):

x = (1+3/4)(32/8) = (7/4)(4) = 7

So the answer is: the number of cups of sugar Erin needs to fill a 32cup pitcher is 7.

Answer 2

We have the next information

`1(1)/(4)\text{ cups of white sugar }\rightarrow8\text{ cups of lemonade}`

First we need to change the 1 1/4 to a fraction

`1\text{ }(1)/(4)=(5)/(4)`

we do the division and we obtain the decimal value 1.25

in order to obtain the number of cups of sugar, we do the next operation, where c is the number of cups needed to do 32 cups

`c=(32*1.25)/(8)=5`

She will need 5 cups of sugar to fill 32 cup pitcher
