Question

Todd wants to make a snack of a number of grapes and slices of cheese. He knows that each grape has 2 calories. The slice of cheese is 155 calories. Todd wants calorie snack using both grape and cheese. What equation could he use to determine the number of grapes he can eat? Part 2: how many grapes can he eat for his 205 calorie snack? Part 3: Todd's friend Francis brings more slices of cheese. How many total slices of cheese are required to make a 515 calories snack if the number of grapes remain the same?

Answer 1

The answer to your question is:

a) C = 2g + 155c

b) g = 25 grapes

c) c = 3

Explanation:

Data

grapes = g = 2 calories

cheese = c = 155 calories

a) Equation, we consider the amount of grapes and the calores given.

Total calories = C = 2g + 155c

b) We consider that the slices of cheese stays the same

2g + 155 = 205

2g = 205 -155

2g = 50

g = 50/2 = 25 grapes

c) Then the number of grapes stays the same

2(25) + 155c = 515

50 + 155c = 515

155c = 515 - 50

155c = 465

c = 465/155

c = 3 slices of cheese
