How do you figure out your ratios

soldi70 [24.7K]

Hello
To find an equal ratio, you can either multiply or divide each term in the ratio by the same number (but not zero). For example, if we divide both terms in the ratio 3:6 by the number three, then we get the equal ratio, 1:2.

Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance ticket and one sam

kogti [31]

Answer:

Advance tickets-$15

Same-day tickets-$20

Step-by-step explanation:

let x be the cost of advance tickets and y cost of same-day tickets:

$x+y=35\ \ \ \ \ \ \ ...i$

Given that there were 40 advance and 25 same-day tickets for a total of $1100:

$40x+25y=1100\\\\8x+5y=220\ \ \ \ \ \ \ \ \ \ \ ...ii$

#Make x the subject in i and substitute in ii:

$x=35-y\\\\\therefore 8x+5y=220, x=35-y\\\\8(35-y)+5y=220\\\\280-8y+5y=220\\\\60=3y\\\\y=20\\\\x=35-y=35-20=15$

Hence, advance tickets cost $15 each while same-day tickets cost $20 each.
