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>

Vilka [71]
The formula for area is length times width, therefor since you already have the length, all you do is 433.37 / 28.7 which = 15.1
