Ok I need help with this math?

Question

Budget Checking: $2.50 Monthly Service Charge, 4 free checks,and additional checks cost 75 cents each.

Regular Checking: $5.00 monthly service charge, 22 cents per check. The service charge is dropped if you keep a $500 Balance.

1) Sandy writes 10 checks per month and has a balance of $200. How much will Sandy

pay per month to use the Budget Checking Account? (Calculate the amount paid for checks first, then add in the monthly service charge.)

I just need this one so I know how to do the rest, please help.

Answer 1

Her balance is less than $500 so you can ignore the balance amount.

First subtract the number of free checks from the total number

10-4=6

multiply that by the cost of each check 6 x .75=$4.50

Then add the monthly service charge

4.50+2.50=$7.00

The full problem can be written out:

(10-4)(.75)+2.5

6(.75)+2.5

4.5+2.5

7

Answer 2

Well, Sandy has the monthly service charge, so that's $2.50.

She gets 4 free checks, so you have to chuck off (subtract) 4 from the 10 she writes during the month--that means she pays for 6 checks times .75 = $4.50.

So with $2.50 + $4.50, she would pay $7.00 on the Budget Plan.

Answer 3

Okay-first add in the $2.50 monthly service charge.

She writes 10 checks-and 4 are free, so 6 are not free.

6 times $0.75 equals $4.50.  2.50+4.50=7$, the amount she will be charged.
