Operations

The science club hosts a bake

sale every year to raise money for

the state robotics competition.

This year, the club earned $20

more than twice what it earned

last year.

Let x represent the amount

raised last year.

Which two words in this problem tell you what operations will be in the algebraic

expression? What do they mean?

More than

Step-by-step explanation

This year the club earned $20 more than twice what it earned last year. Let x represent the amount raised last year.

The two words in this problem which tell us about the operation are "More Than"

This year club earned $20 more than than twice it earned last year. This means, to find the earnings of this year, double the earnings of previous year and add 20 to them.

Since, x represents the earnings of last year, we can represent the earnings of this year as:

Twice of x + 20
