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

Answer: Required expression is,

$\frac{2\times 1\frac{1}{4}+\frac{5}{2}}{\frac{3}{4}}$

Approximately 7 cans are required.

Step-by-step explanation:

Given,

The number of cups required for lasagna recipe = $1\frac{1}{4}$

After doubling lasagna recipe, the number of cups required = $2\times 1\frac{1}{4}$

Also, the number of cups required for each pizza = $\frac{1}{2}$

If the number of pizza = 5,

Then the number of cups required for 5 pizza = $\frac{5}{2}$

So, the total cups required = $2\times 1\frac{1}{4}+\frac{5}{2}$

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

$=\frac{\text{Total cups required}}{\frac{3}{4}}$

$=\frac{2\times 1\frac{1}{4}+\frac{5}{2}}{\frac{3}{4}}$

$=\frac{2\times \frac{5}{4}+\frac{5}{2}}{\frac{3}{4}}$

$=\frac{\frac{10}{4}+\fra{5}{2}}{\frac{3}{4}}$

$=\frac{\frac{10+10}{4}}{\frac{3}{4}}$

$=\frac{\frac{20}{4}}{\frac{3}{4}}$

$=\frac{20}{3}$

$=6.667\approx 7$

Answer 2

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