A customer is buying a $100 drill and two $15 drill bit sets. The customer uses a gift card worth $50 to pay for a portion of their bill. How much cash will the customer pay (before taxes)?

100 + 15 + 15 = 130

130 - 50 = ?

80

To calculate how much cash the customer will pay, we need to consider the total cost of the items they are purchasing and subtract the value of the gift card.

First, let's calculate the total cost of all the items. The drill costs $100, and there are two drill bit sets that cost $15 each. So, the total cost of the drill and two drill bit sets is:

($100 drill) + (2 * $15 drill bit sets)
= $100 + (2 * $15)
= $100 + $30
= $130

Now, we need to subtract the value of the gift card from the total cost. The gift card is worth $50, so we subtract $50 from $130:

$130 - $50 = $80

Therefore, the customer will pay $80 in cash (before taxes).
