Final answer:
To calculate the total pay, multiply the number of boxes made each day by the payment rate of $1.50 per box and then sum up the results. The total pay in this case is $55.50.
Step-by-step explanation:
To find the total pay, you need to multiply the number of boxes made each day by the payment rate of $1.50 per box and then sum up the results.
Day 1: 10 boxes x $1.50 per box = $15
Day 2: 4 boxes x $1.50 per box = $6
Day 3: 15 boxes x $1.50 per box = $22.50
Day 4: 8 boxes x $1.50 per box = $12
Total pay = $15 + $6 + $22.50 + $12 = $55.50
