Answer:
The equation is: [tex]45d+70=880[/tex]
Barry attended preschool for 18 days last month.
Step-by-step explanation:
The number of days, Barry spent at the preschool center last month is [tex]d[/tex].
The cost of preschool is $45 per day. So, the total cost for [tex]d[/tex] days [tex]= \$45d[/tex]
Fixed monthly charge is $70.
So, the total charge of last month [tex]= (45d+70)\ dollars[/tex]
Given that, Samantha paid a total of $880 to the preschool center last month.
So, the equation that represents the situation: [tex]45d+70=880[/tex]
Solving the above equation, we will get........
[tex]45d+70=880\\ \\ 45d=880-70\\ \\ 45d=810\\ \\ d=\frac{810}{45}=18[/tex]
So, Barry attended preschool for 18 days last month.
