The <em><u>correct answer </u></em>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

Does anyone know the answer to this?
Elis [28]

65 + (3x-10) + 2x = 180

65 +5x-10 = 180

55 + 5x =180

5x = 125

x = 125/5 = 25


x = 25

B = 3(25)-10 = 75-10 = 65

C = 2(25) = 50
