Checking account a charges a monthly fee of $10 and a per-check fee of $0.10, and checking account b charges a monthly fee of $12 and a per-check fee of $0.05. how many checks would a person have to write for the two accounts to cost the same? a. 35 b. 50 c. 55 d. 40

Best Account A would have to write 30 checks to equal a total amount of 13.00 for the monthly fee.

30 checks x .10 equal 3.00 dollars + 10 dollar monthly fee = 13.00.

Account B would have to write 20 checks to equal a total amount of 13.00 for the monthly fee.

20 checks x .05 equal 1.00 dollars + 12.00 dollar monthly fee = 13.00.

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
