Final answer:
a. The equation to represent the total cost of the golf outing is $92 = x + $10 + $10. b. The friends paid $72 in greens fees.
Step-by-step explanation:
a. The equation to represent the total cost of the golf outing can be written as:
Total Cost = Green Fees + Club Rental + Cart Rental
Since the green fees are not given, we can denote them as x. The cost of renting clubs for the two players is $5 per set, so the total cost of renting clubs is $10. The total cost of the golf outing is $92, so we can write the equation as:
$92 = x + $10 + $10
b. To find the amount paid in greens fees, we subtract the cost of renting clubs and the cart rental from the total cost of the golf outing:
Greens Fees = $92 - $10 - $10 = $72
