--
Betty and Archie, two seniors, sold cupcakes as a fundraiser to
benefit the school's yearbook. The number of cupcakes that
Archie sold can be given as 20 more than a number, x. Betty
sold five fewer cupcakes than twice a number, x. -
A) Write an algebraic expretssion that can be used to represent the
amount of cupcakes that each senior sold.
Archie:
Betty:-

Archie:  x+20

Betty: 2x-5

Step-by-step explanation:

We are given that The number of cupcakes that  Archie sold can be given as 20 more than a number, x.

So, 20 more than  x = x+20

So, Archie sold cupcakes = x+20

We are also given that Betty  sold five fewer cupcakes than twice a number, x.

So,twice a number, x = 2x

Five fewer cupcakes than twice a number, x. =2x-5

So, Betty sold cupcakes = 2x-5

Hence an algebraic expression that can be used to represent the amount of cupcakes that each senior sold

Archie:  x+20

Betty: 2x-5
