Answer:

C = 60t + 70

Step-by-step explanation:

The total cost of hiring Plumbing Service is given by the equation C = 50t + 70, where C is the total cost in dollar and t is the time in hours.

So, $ 70 is the fixed price and $50 is the rate of charge per hour for the service.

Now if in the next month the rate of charge per hour for the service increased to $60 and the initial charge remains the same then the equation for the total cost of hiring Plumbing Service will become C = 60t + 70. (Answer)

We have to consider the Order of Operations
And Divide the question into different parts
So we first do the Exponent: $2^{5}$ = 32
(3×32-26)=(96-26)=70
Solve the parts in parenthesis
(8-(4-9)=(8-(-5)=(8+5)=13 (minus and minus becomes addition)
Distribute 7
7(13)=91
Now put the equation and equate everything
(3× $2^{5}$ +13(-2))+7(8-(4-9)=70+91=161
Final Answer=161
