Question

For lunch Dregg had a hamburger and potato chips. The hamburger had 375 calories and each chip had 12 calories. If the meal had 639 calories, how many chips did Dregg eat?

Answer 1

So, the number of chips Dregg eat was 22.

Explanation

Suppose, the number of potato chips is $x$

As each chip had 12 calories, so the total calories in $x$ number of chips $=12x$

The hamburger had 375 calories and the meal had total 639 calories. So, the equation will be .......

$12x+375= 639\\ \\ 12x= 639-375=264\\ \\ x=\frac{264}{12}=22$

So, the number of chips Dregg eat was 22.
