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 is earned last year. What is the algebraic expressions?

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
