suppose you have $55 in your bank account. You start saving $10 each week. Your friend has $20 in her account and is saving $15
zhenek [66]
The equation is:
55 + 10 x = 20 + 15 x, where x is number of the weeks.
55 - 20 = 15 x - 5 x
35 = 5 x
x = 35 : 5
x = 7
Answer:
The same amount of money in both accounts will be after 7 weeks.
