Question

A checking account has a balance of $350. A customer makes two withdrawals, one $50 more than the other. Then he makes a deposit of $75. write an expression for the new balance using as few terms as possible.

Answer 1

Explanation:

Initial account balance = A

= $350

Two withdrawals:

Second withdrawal, y = x + 50

Deposit = p

= $75

New balance = n

n = A - (y + x) + p

n = A - (x + 50 + x) + p

Inputting values,

n = 350 - (2x + 50) + 75

Simplifying further,

Expression:

n = 375 - 2x

Where x is the initial amount withdrawn

Answer 2

375-2x

Explanation:

Bal =350

Let 1st withdrawal be x

2nd withdrawal will be x+50

Deposited 75

New Balance =350 - (x+x+50) +75

=350-2x-50+75

=375-2x
