Question

Rob buys 2 sandwiches for $2.50 each and

a bottle of water for $1.25. He pays with a
$10 bill. How much does Rob receive in
change?
$

Answer 1

Rob received $3.75

First, find out how much the 2 sandwiches cost:

2 sandwiches at $2.50 each

$2.50 × 2 = $5.00

1 bottle of water is $1.25

You add the items bought, the sandwiches and the bottle of water, to find out how much was spent

$5.00 + $1.25 = $6.25

Now, to find out how much change Rob received, you subtract the amount purchased to the amount of the bill he paid with.

$10.00 - $6.25 = $3.75
