Representing in fraction for the best understanding

When the exponent is negative, the inversion is made, the numerator becomes the denominator, and the denominator becomes the numerator, and the change of signal from the exponent, which was negative, becomes positive.




c.-1/6

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)
