Answer:
b = $48000, m = $3187.5 / year
Step-by-step explanation:
The equation of a linear function is given as y = mx + b, where m is the rate of change, b is the value of y when x = 0, y = dependent variable and x = dependent variable.
Given that V = mt + b:
b = initial price of the house at 0 years = $48000
V = mt + 48000, At 8 years the house is appraised at $73,500
73500 = 8m + 48000
8m = 73500 - 48000
8m = 25500
m = 3187.5

Markup is the amount a certain seller is adding to the cost to get the selling price of her product. In this problem, Camille Keegan has the selling price of $92.10 and the cost is $62.00. To get the markup, you just have to deduct the cost from the selling price:
$92.10 - $62.00 = $30.10
To get the percent markup, you just have to divide the
markup by the cost of the product:
$30.10/$62.00 = 48.55% markup
a)
20 shirts | 349 + 20(4.8)
40 shirts | 349 + 40(4.8)
60 shirts | 349 + 60(4.8)
(please simplify them yourself)
b) Tn = 349 + n(4.8)
c) (1000 - 349)/4.8 ............... rounded down.
