Question

If there are 52 calories in one chicken nugget and 39 calories in one waffle fry, write an expression to represent the total number of calories consumed if you eat c chicken nuggets and w waffle fries. Next, find out total number of calories consumed if you ate 5 chicken nuggets and 10 waffle fries.

Answer 1

Equation: y = 52c + 39w
Plug in 5 for c and 10 for w
52(5) + 39(10) = 260 + 390 = 650 calories

Answer 2

Multiply calories per nugget by number of nuggets and add to calories per waffle multiplied by number of waffles:

Total calories = 52c + 39w

Now replace the variables with the quantities and find total calories:

Total = 52(5) + 39(10)

Total = 260 + 390

Total = 650 calories
