Answer:
$429.75
Step-by-step explanation:
First, find the tax rate on the sale of the boat: Let r represent that rate. Then,
$12,500r = $562.50. Solving for r, we get r = $562.50 / $12,500 = 0.045
The tax rate is 0.045, or 4.5%.
Applying this tax rate to a boat selling for $9,550:
0.045($9,550) = $429.75. This is the amount of tax on the 2nd boat.
You want to get x on one side so you divide both sides by 7 and 35/7 = 5
