Answer: See explanation
Step-by-step explanation:
Monday
<em>The sale price of the items was $41.40</em>
<em>Mrs. Bolden paid $2.48 in sales tax on her purchase.</em>
<em>Altogether, Mrs. Bolden paid $43.88 for the shirts and flip flops.</em>
Tuesday
<em>The price decreased by approximately 8%</em>
3.44 ÷ 3.75 = 0.917
0.917 × 100 = 91.7
91.7 ≈ 92
100 - 92 = 8
8% of 3.75 is 0.3
3.75 - 0.3 = 3.45
3.45 ≈ 3.44
Wednesday
<em>22 ¹/₂ yrs or 22 yrs if that's easier</em>
127.5 ÷ 1500 = 0.085
0.085 × 100 = 8.5
100 - 8.5 = 91.5
4 1/4 = 4.25
91.5 ÷ 4.25 = 21.5294117647
21.5294117647 × 4.25 = 91.5
21.5294117647 ≈ 21 ¹/₂ yrs
Thursday
If she marked up the price by 40%, that means $15 is 60% the original/selling price.
60% of x = 15
0.6x = 15
Divide both sides by 0.6
x = 25
<em>The selling price is $25 </em>
If you wanted to confirm, 0.6 × 25 = 15
Friday
3 jeans for $42 each
3 × 42 = 126
3 jeans for $126
5 shirts for $27 each
5 × 27 = 135
5 shirts for $135
126 + 135 = 261
6.5% of 261
0.065 × 261 = 16.965
16.965 to the nearest cent is 16.97
<em>She would have to pay $16.97 for tax.</em>
261 + 16.97 = 277.97
<em>She won't have enough money to buy everything she wants since the total price would be over $275.</em>
