You have$200in a savings account and $100 in a checking account. Each week you add $50 to your saving account and $30 to your checking account . Write algebraic expression that represent the amount of money in each bank account after w weeks

The expression is (80w+300)

Step-by-step explanation:

Let

y > the total amount of money in both accounts

s > the amount of money in saving account

c > the amount of money in checking account

w > the number of weeks

we know that

saving account

s=50w+200 > equation A

checking account

c=30w+100 > equation B

To find out the total amount of money in both accounts, sum equation A and equation B

y=s+c

substitute

y=(50w+200)+(30w+100)

y=(50w+30w)+(200+100)

y=80w+300

therefore

The expression is (80w+300)
