Question

Rowan opens a savings account with $25 and saves $75 per month. Reem opens a savings account with $225 and saves $25 per month.

Answer 1

Answer:

a.) y= 75x+25

b.) y= 25x+225

c.) Their account balances will be the same in 4 months and they'll have $325.

Step-by-step explanation:

For A and B: The variable is x which is the amount of months then add the initial amounts without a variable and equal it to y which is the amount in all.

For Rowan, they are saving $75 per month. This is where our variable goes and then we add the intial $25 dollars. The equation is y= 75x+25.

For Reem, they are saving $25 per month. This is where our variable goes and then we add the intial $225 dollars. The equation is y= 25x+225

C. You have to set the equations equal to each other and then solve for x.

75x+25 = 25x+225

Subtract 25 from each side

75x=25x+200

Subtract 25x from each side

50x=200

Divide each side by 50

X=4

For the amount they'll have, just plug 4 into one of the equations.

Rowan : y=75(4)+25

y=325

Reem: y=25(4)+225

y=325
