Springfield have altogether?
(I found other answers but they used 18!?!??) pls help I’m dumb

Answer 1

20 parks

Explanation:

75% is 3/4

15 is 3/4

5 is 1/4

15 + 5 = 20

Think. don't always use algorithm

Answer 2

Answer: 20 parks

Explanation:

Let the total number of parks be y.

Then 75% of y = 15 , that is

`(75)/(100)` x y = 15

75y = 15 x 100

75y = 1500

divide through by 75

y = 1500/15

y = 20

Therefore Springfield have 20 parks altogether
