CKING ACCOUNT Recently Javier received a letter from his bank concerning his checking account. Under his current plan, each check he writes costs 15c, and he pays a monthly fee of $1.60. Under the proposed new plan, each check he writes will cost 12c and there will be a monthly fee of $2.75. What is the minimum number of checks Javier must write monthly so that the new plan will cost him less than the current plan? CHAPTER 6

Explanation / Answer

Let the number of checks be x.

Old plan: $1.6 + 0.15x

New plan: $2.75 + 0.12x

New plan <= current plan

2.75 + 0.12x < = 1.6 + 0.15x

1.15 < = 0.03x

x > = 1.15/0.03

x > = 38.33

Now, x cannot be decimal.

So, x = 39

So, the minimum number of checks which he should write = 39
