The school bookstore rents graphing calculators for $5 per month. It also collects a non-refundable fee of $10.00 for the school year. a. Write the rule for the total cost (c) of renting a calculator as a function of the number of months (m). (Remember slope - intercept form and replace x and y with the variables they are using here)

b. How much is owed if a person rents graphing calculators for 6 months? Show your work.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.

,, add !

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
