Since the tax is the same for each, then tax = 9.5% of Total Amount spent (150 + 25 + 30) = 9.5/100 * 205 = 19.475


Therefore Total Amount spent = 205 + 19.475 = 224.475 \(\approx\) $224

Option D

approx total cost = 205
Amount spent = 205*1.095 = 224.475 ≈ 224

Hence, OA is (D).

By approximating all values we get
Cell phone - 150
Cover - 25
Charger - 30
Total = 205
Total tax = 205 * 0.095= 19.475

Total amount after tax = 205 + 19 = 224. Something

Answer - D

Solution:

Instead of finding the exact cost, let’s find the approximate cost since we are asked to find an amount that is closest to the amount Maria actually spent. We can approximate the total cost before tax as:

150 + 25 + 30 = $205

Since the tax rate is 9.5%, let’s round that up to 10%. Since the total cost is approximately $205, let’s round that down to $200. Therefore, the total cost after tax is approximately:

200 x 1.1 = $220

Since $224 is closest to $220, $224 is the correct answer.

Answer D

149 ≈ 150 , 24 ≈ 25 and 29 ≈ 30

150 + 25 + 30 = 205

tax = 9.5% ≈ 10%

Tax = 205 + 205*0.10 = 225.5
