To find out how much Alberto paid in total, we need to calculate the cost of the ping pong balls and then add the cost of the bat.
-
Cost of the ping pong balls:
- The pack contains 6 ping pong balls, and each ball costs 50 cents.
- Cost of 6 ping pong balls = 6 balls × 0.50 dollars/ball = 3 dollars.
-
Cost of the bat:
- The bat costs $15.
-
Total cost:
- Total cost = Cost of ping pong balls + Cost of bat
- Total cost = $3 + $15 = $18.
Thus, Alberto paid $18 in total.
