Explanation of Solution

Given:

The chess club is having a bake sale to raise money for a tournament. The club must raise at least three times what they raised at the last bake sale. What is the minimum amount they must raise if the last bake sale raised $45?

4 options are given: $\text{A}:\$15;\text{B}:\$45;\text{C}:\$90;\text{D}:\$135$

The club must raise at least three times what they raised at the last bake sale.

The inequality symbol used for the term at least is $\ge$

The last bake sale raised $45.
