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 + 2(15) - 50 = ?

To determine the amount of cash the customer will pay before taxes, we need to calculate the total cost of the items and then subtract the value of the gift card.

First, let's find the total cost of the drill and the drill bit sets. The drill costs $100, and there are two drill bit sets, each costing $15.

Total cost of the drill: $100
Total cost of two drill bit sets: 2 * $15 = $30

Next, we calculate the sum of the costs:
$100 + $30 = $130

So, the total of all items together is $130.

The customer uses a gift card worth $50 to pay for a portion of their bill, so we subtract the value of the gift card from the total cost to find the amount of cash the customer will pay:

$130 - $50 = $80

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