Given the statement:
Lynn takes her puppy, olive, to 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.
Determine the equation and how many days was Lynn there.
Solution:
The equation for the given can be represented as,
21x + 48 = 426
x = number of days.
Now in order to determine the number of days we simply needed to solve for x. The first step is to transpose 48 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
21x = 426 - 48
21x = 378
Divide both sides by 21 in order to determine the value of x.
21x/21 =378/21
x = 18
Final answer:
18 days.
