Question

Adam eats 20 % of a pizza, Bethany eats another 1/3 of the pizza, and Charlie eats the remaining 14 slices. How many slices total did the pizza originally have?

Answer 1

The pizza originally have 30 slices.

What is linear equation?

An equation in which the highest power of the variable is one is known as linear equation.

We will find number of pizza slices as shown below:

Let pizza originally have x slices.

Adam eats 20% of a pizza

= 0.2x

Bethany eats 1/3 of pizza

=1/3(x)

Charlie eats the remaining 14 slices

0.2x+1/3(x)+14=x

14 = x - 0.2x - 1/3(x)

14 = x - x/5 - x/3

14 = (15x - 3x - 5x)/15

14*15 = 7x

By dividing both sides by 7, we get

30 = x

x = 30

Hence, the pizza originally have 30 slices.
