Answer:
Number of plain cookie boxes sold = 785 boxes
Step-by-step explanation:
Given: Cost of a chocolate chip cookie box = $1.25
Cost of a plain cookie box = $0.75
Total number of boxes sold = 1585
Total cost of the sold boxes = $1588.75
Let, number of plain cookie boxes sold = x
Number of chocolate chip cookie boxes sold = 1585 - x
So,
Total cost = total cost of the sold plain cookie boxes + total cost of the sold chocolate chip cookie boxes
$1588.75 = x ($0.75) + (1585 - x) ($1.25)
1588.75 = 0.75 x + 1981.25 - 1.25 x
0.5 x = 392.5
Therefore,
<u>Number of plain cookie boxes sold: x = 392.5 ÷ 0.5 = 785 boxes</u>

Answer:
<h2>d=4</h2>
Step-by-step explanation:
Let's solve your equation step-by-step.
11=−d+15
Step 1: Flip the equation.
−d+15=11
Step 2: Subtract 15 from both sides.
−d+15−15=11−15
−d=−4
Step 3: Divide both sides by -1.
−d/−1=−4/−1
