Answer:
The price of collection of novels before taxes was <u>$409.10</u>.
Step-by-step explanation:
Given:
Ava bought a collection of hardcover novels and paid $450 including sales tax.
The sales tax is 10%.
Now, to find the price of collection of novels before taxes.
Let the price of collection of novels before sales tax be
.
The price of collection of novels including sales tax = $450.
Rate of sales tax = 10%.
Now, to get the price before sales tax by putting an equation:




<em>Adding both sides by 0.10</em>
<em> we get:</em>
<em />
<em />
<em>Dividing both sides by 1.10 we get:</em>

Therefore, the price of collection of novels before taxes was $409.10.
3 slots
1st slot has 10 possible people
2nd slot has 9 possible people (1 less than previous)
3rd slot has 8 possible people
so there are 10*9*8 ways or 720 ways
First we need to find the total annual costs for both the plans.
In case of leasing:
Fixed monthly cost = $420
So, yearly cost = 420 x 12 = $5040
Cost per mile = $0.08
For x miles driven, the cost per year for leasing will be = 5040 + 0.08x
In case of purchasing:
Fixed yearly cost = $4600
Cost per mile = 0.10
For x miles driven, the cost per year for leasing will be = 4600 + 0.10x
We want to find for what number of miles will the cost of leasing will be no more expensive than the cost of purchasing.
So,
Cost of leasing ≤ Cost of purchasing
5040 + 0.08x ≤ 4600 + 0.10x
440 ≤ 0.02x
22000 ≤ x
Thus, if if the number of miles driven are equal to or less than 22,000 leasing will be no more expensive than purchasing.
