Answer:
<h3><em>D. 880 = 45d + 70; 18 days.</em></h3>Step-by-step explanation:
We are given fixed monthly charge = $70.
The cost of preschool per day = $45.
Number of days = d.
Total cost of d days = cost per day × number of days + fixed monthly charge.
Therefore, we get equation
880 = 45×d+70
<h3>880 = 45d +70.</h3>Now, we need to solve the equation for d.
Subtracting 70 from both sides, we get
880-70 = 45d +70-70
810=45d
Dividing both sides by 45, we get
18=d.
Therefore,<em> 18 days Barry attended preschool last month.</em>
<em>Therefore, correct option is D option.</em>
<h3><em>D. 880 = 45d + 70; 18 days.</em></h3>
We know for our problem that Rachel makes $10 per hour. Since
represent the number of hours that she works, 
will be the total amount that she will make for working hours. We also know that she sells bracelets for $5 each. Since 
represents the number of of bracelets that she sells, 
will be her total revenue for selling bracelets. We also know that she needs to earn at least $200 a week to cover her expenses, so the sum of and must be equal or greater than 200:
