A local kids play sold 8 adult tickets and 9 child tickets for a total of $205. On day two they sold only 4 adult tickets and 3

Naya [18.7K]

Answer:

The price of 1 adult ticket is $ 11 and price of 1 child ticket is $13

Step-by-step explanation:

Let x be the cost of 1 adult ticket

Let y be the cost of 1 child ticket

Cost of 8 adult tickets = 8x

Cost of 9 child tickets = 9y

We are given that A local kids play sold 8 adult tickets and 9 child tickets for a total of $205

So, 8x+9y=205 ----- 1

Cost of 4 adult tickets = 4x

Cost of 3 child tickets = 3y

We are given that 4 adult tickets and 3 child tickets for a total of $83.

4x+3y=83 ----2

Plot 1 and 2 on graph

8x+9y=205 -- Red line

4x+3y=83 -- Blue line

Intersection point provides the solution

So, Intersection point =(11,13)

So, The price of 1 adult ticket is $ 11 and price of 1 child ticket is $13

The ratio of 10 to pencil is 2/7 if you count 84 pencil how many pain would you expect to find

frosja888 [35]

How much pain would you find? hopefully none, since you'd have lots of pens and pencils :).

$\bf \cfrac{pens}{pencils}\qquad \cfrac{2}{7}\qquad 2:7\qquad \qquad \cfrac{\stackrel{pens}{p}}{\stackrel{pencils}{84}}=\cfrac{2}{7}\implies p=\cfrac{84\cdot 2}{7}$
