Respuesta :

45d+70=$880. $880-70=$810. 810/45=18

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.
