Question

a school is raising money for a book fair. they already have $150 and plan to raise $75 each day of the week - long book fair. if they need $600 to fund the fair, what is the minimum number of days they must raise money to meet their goal? set up an equation and solve.

Explanation:

Step1: Define variable and equation

Let \( d = \) number of days. Equation: \( 150 + 75d \geq 600 \)

Step2: Subtract 150 from both sides

\( 75d \geq 600 - 150 \) → \( 75d \geq 450 \)

Step3: Divide by 75

\( d \geq \frac{450}{75} \) → \( d \geq 6 \)

Answer:

6 days
