Question

Jade has $451.89 in her checking account. After 3 checks, each for the same amount, are deducted from her account, she has $358.92 left in her account.

Assume she makes no other withdrawals or deposits. Which equations represent c, the amount of one check, in dollars? Check all that apply.

Answer 1

well, if we wanted to find the amount deducted in each check, first we would want to find the difference between the initial and final balance, then divide by the number of checks

which equation best represents this idea?

Answer 2

hm.

so one way we could express this is

initial amount - 3checks = final amount

which equation might this be?

Answer 3

451.89 - 358.92 = 92.97 divided by 3 = 30.99

Answer 4

well that's a good start, but keep in mind the question is not asking for the value of a check, it is asking for an equation

so if we interpret the problem as

initial amount - 3 checks = final amount

which equation best matches this scenario?

Answer 5

4,5,& 6

Answer 6

almost

4+6 are good

5 can't be it because it takes the final amount - initial amount but then multiplies by 3 instead of dividing

Answer 7

any attempts on 1-3?

if we plug in values:

initial amount - 3 checks = final amount
becomes

451.89 - 3checks = 358.92

between equations 1, 2, 3, which one(s) match this idea?
