PLS HELP IM BEING TIMED 2 FOR BRAINLIEST

Phyllis is going ice skating.
• the cost to rent figure skates for x hours is given by the function
f(x) = 1.50x + 2.00.
• the cost to rent hockey skates for x hours is given by the function
h(x) = 2.00x +1.50.

If phyllis rents skates for 3 hours, how much cheaper would figure skates be than
hockey skates?

(Note: Express the answer as dollars.cents.

Answer 1

Answer:

figure skates will be $1 cheaper.

Explanation:

given equation:

• to rent figure skates : f(x) = 1.50x + 2

• to rent hockey skates : h(x) = 2x +1.5

solve for rent of figure skates:

f(x) = 1.50x + 2.00

f(3) = 1.50(3) + 2.00

f(3) = 6.5

solve for rent of hockey skates:

h(x) = 2x + 1.5

h(3) = 2(3) +1.5

h(3) = 7.5

cheaper - figure skates than hockey skates:

$7.5 - $6.5

$1
