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? a. 880 = 90d + 45; 9 days b. 880 = 70d - 45; 21 days c. 810 = 45d; 19 days d. 880 = 45d + 70; 18 days

Option D

D. 880 = 45d + 70; 18 days

Step-by-step explanation:

We know that the cost of preschool is $ 45 per day plus a monthly fee of $ 70.

We also know that a total of $ 880 was paid last month

To write an equation that represents this situation, let us call d the number of days that Barry attends school

So the cost was:

Now we solve the equation for the variable d

The answer is the option D

yes, i heard the "tea" with james charles and a few other beauty gurus. i believe charles is in the wrong and i believe tati the most. tati didn't lie about james charles but may have exaggerated because he never sexually assaulted anyone. jeffery star is a really good friend to all and out anyone that needs it, until you mess with one of his "sisters"! james will never rise over jeffery or tati, he's way to sensitive and dramatic to rise about them. i think all three of them will make up and be friends again because they always get over it.

i hope this with your

x=0.8898305 is the answer to that equation
