Writing Equations

Scott works on cars. He charges $35 for each car plus $7 per hour. Write an equation that represents this scenario if Kylie's car bill was $63.

• 7x + 35 = 63
• 7x = 63
• 7x - 35 = 63
• 35x + 7 = 63

Jimmy spent $33 on Amazon. This was $4 more than half of the amount of money Shane spent.

Which equation best represents the amount of money Shane spent ?

• $4+2m=33$

Ellie bought cookies and cupcakes from Giant for $102.44. If she spent $36.44 on cookies and the cupcakes are $11 per box, which equation represents how many boxes of cookies she bought?

• 102.44 + 36.44x = 11

• 102.44x + 11 = 36.44

• 11x + 36.44 = 102.44

• $\frac{11}{x}+\ 36.44\ =102.44$
