QUESTION 20

Answer 1

Answer:

Explanation:

Let the protein contained in pizza be m gram .

calories contained by 17 g of fat = 17 x 9  kcals = 153  kcals .

calories contained by 25 g of carbohydrate = 25 x 4  kcals = 100 kcals .

calories contained by m  g of protein  = m  x 4  kcals = 4 m  kcals .

Total calories of slice of pizza = 153 + 100 + 4m kcals

= 253 + 4m kcals

Given ,

253 + 4m = 750

4m = 497

m = 124.25 g .

120 g ( rounded to two significant  figures )
