Question

Jada is making lasagna and pizzas for a large party.Her lasagna recipe call for 1 1/4 cups of tomatp paste, and her pizza recipe uses 1/2 cupb of tomato paste per pizza. She will double her lasagna recipe and make 5 pizzas. Write and evaluate an an expression for how many 3/4-cup cans of tomato paste she need in all.

Answer 1

Your answer would be: 20/3 = 6 2/3. Hope I helped!

Answer 2

Answer: Required expression is,

`(2* 1(1)/(4)+(5)/(2))/((3)/(4))`

Approximately 7 cans are required.

Explanation:

Given,

The number of cups required for lasagna recipe =
`1(1)/(4)`

After doubling lasagna recipe, the number of cups required =
`2* 1(1)/(4)`

Also, the number of cups required for each pizza =
`(1)/(2)`

If the number of pizza = 5,

Then the number of cups required for 5 pizza =
`(5)/(2)`

So, the total cups required =
`2* 1(1)/(4)+(5)/(2)`

Hence, number of '3/4-cup cans' of tomato paste

`=\frac{\text{Total cups required}}{(3)/(4)}`

`=(2* 1(1)/(4)+(5)/(2))/((3)/(4))`

`=(2* (5)/(4)+(5)/(2))/((3)/(4))`

`=\frac{(10)/(4)+\fra{5}{2}}{(3)/(4)}`

`=((10+10)/(4))/((3)/(4))`

`=((20)/(4))/((3)/(4))`

`=(20)/(3)`

`=6.667\approx 7`
