The correct answer is:
B. 14
Explanation:
Let x be the number of days. On day 1, we begin with 64 orders. We gain 18 orders per day; this is 18x, and gives us
64+18x.
We also make 28 crates per day, which decreases the number of crates we need by 28 per day; this is -28x, and gives us
64+18x-28x
Combining like terms, we get
64-10x
For day 5, we replace x with 5:
64-10(5) = 64-50 = 14
