Question

You and four friends go to Johnny Rockets. You all split the bill equally. Each person’s share was $6.50. How much was the original bill? Let a represent the amount of the original bill.

Answer 1

the answer is $26.00 because

$6.50*(4+1)= $6.50*5, which is $26.00.
hope this helps you.

Answer 2

If "a" represents the original bill, your equation would look like this;
a = 6.5*(5)
6.5 * (5) = $32.50
