jack owes his brother 100$. if he pays his brother back 30$ initially, the 5$ each week how long until he has finished paying his brother back? write an equation and solve it.
( 30+5x=100)
( 30+5x=100) You got it right!. Just solve for x
30+5x = 100
5x = 100 - 30
5x = 70 divide both sides by 5
x =70/5
x= 14 weeks - that will Jack to pay off his brother.
write an equation and solve it.
