Respuesta :

Answer:

21

Step-by-step explanation:

Answer: they should sell at least, 21 T shirts

Step-by-step explanation:

Let x represents the number of T shirts that they sell at the fundraiser.

The school band gets $5 for each T-shirt they sell at a fundraiser. If $45 has been raised so far, then the expression representing the total amount that they would raise from selling extra x T shirts is expressed as

5x + 45

They have a goal of raising $150. The expression for the number of more T shirts that they have to sell to reach or exceed the goal is

5x + 45 ≥ 150

5x ≥ 150 - 45

5x ≥ 105

x ≥ 105/5

x ≥ 21
