Question

Christie purchased a scarf marked $15.50 and gloves marked $5.50. Both items were on sale

for 20% off the marked price. Christie paid 5% sales tax on her purchase. How much did she
spend?

Answer 1

Answer: $17.64

Step-by-step explanation:

The two items combine to a total price of 15.50+5.50 = 21 dollars before any discounts or taxes are applied.

If she saves 20%, then she still pays the remaining 80%. So 0.80 is one multiplier we'll apply. We'll also apply 1.05 to represent a 5% increase due to the sales tax.

The amount she spends, after the discount and tax are applied, is 21*0.80*1.05 = 17.64 dollars

Answer 2

Christie spent 17.64$.

Step-by-step explanation:

0.2 x 15.50 = 3.1

15.50 + 3.1 = 12.4

0.2 x 5.50 = 1.1

5.50 - 1.1 = 4.4

12.4 + 4.4 = 16.8

0.05 x 16.8 = 0.84

0.84 + 16.8 = 17.64
