In order to answer the question we need the lengths to do the math.
Plugging in x=-2, you get:
2(-2)^2+5(-2)=2*4-10= -2
Therefore, f(-2)= -2
Deposit = $75 = 30%
(30/100)x = 75
(3/10)x = 75
0.3x = 75
x = 75/0.3
x = 250
Total cost = $250
deposit = $ 75
Total - deposit = $175
Thus, Marc owe $175 for the rug.
Answer:
$1.08 per day times 8 days.
$1.08 x 8 = $8.64 owed
Hailey is only paying 1/4. When talking about money, 1/4 = $0.25.
$8.64 x $0.25 = $2.16
OR
You can calculate as $8.64 x 1/4 and get $2.16
