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)
Answer: The answer is not -7 it is in fact -31.
Step-by-step explanation:
5 - ( 6^2 ) / 4 - 3
6^2 = 36
5 - ( 6^2 ) = -31
4 - 3 = 1
5 - 36 / 1 = -31 / 1 = -31
So anything divided by 1 is = to itself.
Answer C : 3x^2+7xy-2y^2
equivalent to the following expression


Combine like terms

2x^2 + x^2 is 3x^2
4xy+3xy is 7xy
-y^2-y^2 is -2y^2
So expression becomes

Answer C is correct
