Question

Can someone explain this

Answer 1

Aaron has $53 in his account and he spends $3.25 per lunch.

After spending money the balance reflects the amount left in account.

So after paying for 4 lunches the balance is:

• 53 - 4*3.25 = 40

After paying for 6 lunches the balance is:

• 53 - 6*3.25 = 33.5

After paying for n lunches the balance is:

• 53 - n*3.25 =
• 53 - 3.25n
