Question

a parking lot holds 450 cars. the ratio of full size cars is 11:4
how many full size cars will the lot hold....pls send specific and step wise answer​

Answer 1

Answer:

A ratio of 11:4 means that of every 15 cars 11 are full-sized, i.e 330 of 450

Well a system of linear equations would be

F+C = 450

F/C=11/4 => 4F=11C =>F=11C/4

Substitute in the 1st equation:(11/4)C+ C = 450

15C=1800 and C=120 and F= 330

Answer 2

Answer:

Ratio 11:4 means out of 15 car, 11 are fuull sized and other 4 are not. Therefore 330 are full-sized and other 120 are not.

now some linear equations are-F+C=450

and F/C=11/4or, 4F=11C or, F=11/4C

replacing this value of F in 1st equation we get, F+C=450

or, (11/4)C +C=450

or, 15C/4=450

or, C=450*4/15=120

And, F=330
