Answer:
139
Step-by-step explanation:
Substitute x for 15.
9(15)+4
Then multiply:
135+4
And then add:
139
5x+9 = 10x-9
Take 5x from both sides
9 = 5x-9
Add 9 to both sides
18 = 5x
Divide by 5
3.6=x
Answer:
$162.50
Explanation:
The total amount to be paid is 7500+5(7500)(0.06)=$9750.
There were a total of (5)(12)=60 payments, so each payment is 9750/60 = $162.50.
34.95 x 18%= 6.29
34.95-6.29= 28.66
$28.66 is the sale price
