-

-

--

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
