Question

Samantha sends her son, barry, to a preschool center on certain days. The cost of preschool is $45 per day along with a fixed monthly charge of $70. Last month, samantha paid a total of $880 to the preschool center. Let d represent the number of days barry spent at the preschool center last month. Which equation represents this situation, and how many days did barry attend preschool last month?

Answer 1

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

Answer 2

Answer:

The equation is:  $45d+70=880$

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 $d$.

The cost of preschool is $45 per day. So, the total cost for $d$ days $= \ 45d$

Fixed monthly charge is $70.

So, the total charge of last month  $= (45d+70)\ dollars$

Given that, Samantha paid a total of $880 to the preschool center last month.

So, the equation that represents the situation:   $45d+70=880$

Solving the above equation, we will get........

$45d+70=880\\ \\ 45d=880-70\\ \\ 45d=810\\ \\ d=\frac{810}{45}=18$

So, Barry attended preschool for 18 days last month.
