Final answer:
To determine the change Carson will receive, calculate the total cost for three packs of star stickers and tape, subtract this from the amount given at the register, resulting in a change of $21.
Step-by-step explanation:
To calculate how much change Carson will get back after purchasing his glow in the dark star stickers and two-sided tape, we first need to determine the total cost of the items. He wants to buy three packs of star stickers at $14 per pack and one pack of two-sided tape for $12.
- Multiply the cost of one pack of star stickers by the number of packs: $14 × 3 = $42.
- Add the cost of the two-sided tape: $42 + $12 = $54.
- Subtract the total cost from the amount of money Carson gives to the cashier: $75 - $54 = $21.
Therefore, Carson will get $21 in change when he gives the cashier $75.
