Question

Monica earns $140 per week plus $15 for every painting she sells at the gallery. She wants to earns at least $200 this week..How many paintings ,p,does she needs to sell to reach her goal . Write and solve an inequality to represent the situation

Answer 1

The minimum number of paintings Monica needs to sell is 4 to reach her goal.

Explanation:

Let

p-----> the number of paintings that Monica needs to sell

we know that

`140+15p\geq 200`

Solve for p

Subtract 140 both sides

`15p\geq 200-140`

`15p\geq 60`

Divide by 15 both sides

`p\geq 60/15`

`p\geq 4\ painting`

The minimum number of paintings Monica needs to sell is 4 to reach her goal.
