Answer:
They buy at wholesale and sell at an 80% markup. The retail prices are;
0 - 20 pairs.
= 25 * 1.80
= $45.00
21 - 40 pairs
= 23 * 1.80
= $41.40
41 - 60 pairs
= 21 * 1.80
= $37.80
61 - 80 pairs
= 19 * 1.80
= $34.20
81 or more pairs
= 17 * 1.80
= $30.60
500 is the correct answer to this question because the distance from -500 to 0 is 500
Answer:
x = 27
Step-by-step explanation:
4x + 7 = 5(x - 4)
4x + 7 = 5x - 20
4x - 5x = -20 - 7
-x = -27
x = 27

she scored 42
Step-by-step explanation:
The <em>first five</em> terms of the <em>recursive</em> sequence are 5, 12, 19, 26 and 33.
<h3>How to use recursive equations to generate a series</h3>
In this question we have a <em>linear recursive</em> equation that requires the value of the <em>immediately previous</em> element to generate the next one. Then, we need to evaluate the expression for the first five elements:
i = 1
a₁ = 5
i = 2
a₁ = 5, a₂ = a₁ + 7
a₂ = 5 + 7
a₂ = 12
i = 3
a₂ = 12, a₃ = a₂ + 7
a₃ = 12 + 7
a₃ = 19
i = 4
a₃ = 19, a₄ = a₃ + 7
a₄ = 19 + 7
a₄ = 26
i = 5
a₄ = 26, a₅ = a₄ + 7
a₅ = 26 + 7
a₅ = 33
The <em>first five</em> terms of the <em>recursive</em> sequence are 5, 12, 19, 26 and 33.
