A parking garage has 6 levels. Each level has 15 rows. Each row has the same number of parking spaces. There are 2,250 parking s

VladimirAG [237]

Answer:

$25$

Equation: $90x=2250$

Step-by-step explanation:

Let parking spaces in each row $=x$

In $1$ level there are $15\ rows$ so total number of parking spaces in 1 level $=15\times x=15x$

There are $6$ level so total number of parking spaces $=6\times 15x=90x$

$90x=2250\\\\x=\frac{2250}{90}\\\\x=25$
