A customer buys 15.78 worth of gasoline and one can of pepsi price .75. You receive a 20 bill in payment. What is the change?
20 - (15.78 + 0.75) = ?
$3.47
To determine the change, we need to subtract the total amount the customer spent from the amount they paid with the $20 bill.
First, let's calculate the total amount the customer spent. The customer spent $15.78 on gasoline and $0.75 on a can of Pepsi. We add these two amounts together:
$15.78 + $0.75 = $16.53
So, the total amount the customer spent is $16.53.
Now, we can calculate the change by subtracting the total amount spent from the payment received. The customer paid with a $20 bill, so we subtract the total amount spent from $20:
$20 - $16.53 = $3.47
Hence, the change the customer will receive is $3.47.
