Question

For 9x + 25 = 88, Deena wrote the situation “I bought some shirts at the store for $9 and received a $25 discount. My total bill was $88. How many shirts did I buy?”

b. Rewrite the equation to match Deena’s situation

Answer 1

Explanation:

9x + 25 = 88

9x = - 25 = 88

9x = - 63 (divide both sides by 9)

x = - 7

CHECK:

9x + 25 = 88

9 (-7) = 88 - 25

- 63 = - 63
