STEP 1

Assumptions1. The cost of a round of mini-golf is $4.50. The cost is directly proportional to the number of rounds played3. There are no discounts or additional charges based on the number of rounds played

STEP 2

We need to find the total cost of playing1,2,, and4 rounds of mini-golf. We can do this by multiplying the cost of a single round by the number of rounds.
$$Total\, cost = Number\, of\, rounds \\times Cost\, per\, round$$

STEP 3

Now, plug in the given values for the number of rounds and the cost per round to calculate the total cost for each case.
For1 roundTotal\, cost =1 \\times \($\).50

STEP 4

Calculate the total cost for1 round.
Total\, cost =1 \\times \($\)4.50 = \($\)4.50

STEP 5

Repeat the process for2,3, and4 rounds.
For2 roundsTotal\, cost =2 \\times \($\)4.50

STEP 6

Calculate the total cost for2 rounds.
Total\, cost =2 \\times \($\)4.50 = \($\)9.00

STEP 7

For3 roundsTotal\, cost =3 \\times \($\)4.50

STEP 8

Calculate the total cost for3 rounds.
Total\, cost =3 \\times \($\)4.50 = \($\)13.50

STEP 9

For4 roundsTotal\, cost =4 \\times \($\)4.50

STEP 10

Calculate the total cost for4 rounds.
Total\, cost =4 \\times \($\)4.50 = \($\)18.00

The total cost is directly proportional to the number of rounds of mini-golf purchased because the ratios between the quantities are the same unit rate.
The total cost for,,3, and4 rounds of mini-golf are $4.50,$9.00, $13.50, and$18.00 respectively.
