The total cost of hiring paul the plumber is a function of the required number of hours needed to complete the repair. paul charges $40 per hour up to maximum of 8 hours, plus a $75 service charge what is the greatest value in the range for this situation

Paul surely charges 75 dollars, and then he adds 40 dollars per hours. This means that the expression for the money he asks is

where is the amount of money and is the number of hours.

Since can be at most 8, this is the case that generates the highest money, so if we plug we have

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
