Question

Sarah has $200 to spend. She buys a chair for x dollars and pays 6% sales tax. She has y dollars left. What equation models this situation?

A. 200 - 0.06X = Y
b. 200 - 1.06x = y
C. 200 + 1.06X = Y
D. 200 = 0.06X

I chose answer A. Is that the correct answer? If not please show me how to get the correct answer.

Answer 1

b - because she starts with 200 and spends

x dollars + sales tax .06x

x + 0.6x = 1.06x

Subtract what you spent with tax.
1.06x from the 200.
