Question

Eleanor must earn at least 70 points for her book report project. So far on the rubric she has 54 points. Write and solve an inequality to show how many points Madeline needs.

Answer 1

`x + 54\ge 70`

`x \ge 16`

Explanation:

Given

`Total = 70` (at least)

`Accumulated = 54`

Required

Express as an inequality

In inequalities, at least means
`\ge`

So, the expression is:

`x + Accumulated \ge Total`

Where x represents the additional points

`x + 54\ge 70`

Solve for x

`x \ge 70 - 54`

`x \ge 16`

Hence, she needs at least 16 points
