Answer:
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
Answer: $17.64
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
