Lynn takes her puppy, olive, to a doggy daycare. the price for the daycare is $21 per day along with a monthly admission fee of $48. last month lynn paid a total of $426. which equation can be used to find the number of days, d, that olive spent at daycare, and how many days was she there?

Let d = number of days.

$21 per day is represented by 21d.

A fixed fee of $48 is simply 48.

The total cost is 21d + 48.

The total cost for last month was $426, so we let our cost expression equal 426 giving us the equation

21d + 48 = 426

Now we solve for d.

Subtract 48 from both sides.

21d = 378

Divide both sides by 21.

d = 18

Since we let variable d represent the number of days, we conclude that Olive spent 18 days at the daycare.

A. 21d + 48 = 426; 18 days

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
