Question

Maria and Tim sold candy bars for a fundraiser. Maria sold seven less than twice the number of candy bars that Tim sold. In total, Maria and Tim sold 137 candy bars. How many bars did Maria sell?

Answer 1

Let the number of candies sold by Tim be x

Let the number of candies sold by Maria be 2x-7

now, By the question

x+2x-7=137

or, 3x=137+7

or, x= 144÷3

x= 48

Now, Maria sold= 2x-7

= 2×48-7

= 89

therefore, Maria sold 89 bars.
