Professional or union dues, license fees, out of pocket insurance premiums, child care, mortgage interest, state and local tax. There are many more...
Plug in 2 wherever you see 'a'
3(2) + 5(2)(2)
1. 3×2 = 6, so:
6 + 5(2)(2)
2. 5×2=10, 10×2=20, so:
6 + 20
The final answer is 26.
So when one goes up, the other goes down. This is an inverse equation.
An inverse equation looks like this: y = 1/x
In this case, when parking fee (f) decreases, cars (c) increase.
You know which side to put each variable on using the chart they gave you.
f | c
20.00 15 (20.00 = x/15) x=300
30.00 10 (30.00 = x/10) x=300
So your equation in this case is f = 300/c
Knowing that, plug in the fee of 6.00
6 = 300/c Multiply both sides by c.
6c = 300 Divide both sides by 6.
c = 50 cars
Answer:
19.26
Step-by-step explanation:
price sold for= 12×150%
= 18
total cost = 18 × 107%
= 19.26
