The skating rink charges $0.75 to rent skates and $1.25 per hour to skate. Which equation can be used to find the number of hours (h) someone skated if he or she was charged
$4.50?

a) 0.75 + 1.25 = 4.50
b) h(0.75 + 1.25) = 4.50
c) 0.75 + 1.25h = 4.50
d) 0.75h + 1.25 = 4.50

C.

It can be read as...

".75 was charged for skates, and 1.25 was charged per hour for a total of 4.50."

No other answer choice has this. A does not have the variable h, B includes .75 which is NOT charged per hour, as well as D.

I hope this helps you!

replace the variables in the orignal problem with the numbers you were given

(3)^3-2(5)^2-3(3)^3+(-3)^4

which equals -23
