Total cost = a + (13a/100)
<u>Step-by-step explanation:</u>
Let the price of the monster truck be 'a'
He should pay 13% tax
Total cost = price of the truck + tax
Total cost = a + (13a/100)
The equation to represent the total cost is
Total cost= a + (13a/100)
Percent change = (new number - old number)/(old number) * 100
percent change = (127 - 136)/(136) * 100
percent change = -6.62%
Since the percent change is negative it is a percent decrease.
Answer: 6.62% decrease.
