Hey Jiskha! I need help again...

Joe will go to the swimming pool on 20 different days this month.
• A one-day pass to the pool is $2.25.
• A monthly pass to the pool is $30.00.
How much money will Joe save by buying a monthly pass?

I got 45 but thats not one of the answer choices.. :( Please help!

$45 is the amount he'd pay for the month without a monthly pass.

But the question asks how much he'd save with a pass.

Ohhh so like $15?

Yes, $15.

To solve this problem, we need to find out how much Joe would spend by buying one-day passes for 20 different days and compare it to the cost of a monthly pass.

To calculate the cost of one-day passes, we need to multiply the cost of a one-day pass by the number of days Joe will go to the pool.

Cost of one-day pass = $2.25
Number of days Joe will go to the pool = 20

Cost of one-day passes = $2.25 x 20 = $45.00

Now we can compare this with the cost of a monthly pass, which is $30.00.

To find out how much money Joe will save by buying a monthly pass, we subtract the cost of one-day passes from the cost of a monthly pass.

Savings = Cost of one-day passes - Cost of monthly pass
Savings = $45.00 - $30.00
Savings = $15.00

Therefore, Joe will save $15.00 by buying a monthly pass instead of 20 one-day passes.
