Santo paid $16.25 to buy 5 children tickets and 1 adult ticket. Hulda paid $24.00 to buy 4 children tickets and 3 adult tickets.

Answer:

The price of an adult ticket it $5

Step-by-step explanation:

To solve this, we would find the system of equations. We would set up two equations that will represent the situation.

Let c = price per children ticket

Let a = price per adult ticket

Santo:

5c + 1a = 16.25

Hulda:

4c + 3a = 24

5c + 1a = 16.25 -> a = 16.25 - 5c

4c + 3a = 24

4c + 3(16.25 - 5c) = 24

4c + 48.75 - 15c = 24

-11c + 48.75 = 24

-48.75 -48.75

-11c = -24.75

/-11 /-11

c = 2.25

5c + a = 16.25

5(2.25) + a = 16.25

11.25 + a = 16.25

-11.25 -11.25

a = 5

a = $5 , c = $2.25

When a jar of fruit is 2/3 of the way full it can hold 2 1/4 cups of fruit what fraction of the jar is full when it only contain

Natali [406]

Answer:

8/27

Step-by-step explanation:

<h2><u>Fractions</u></h2>

a jar of fruit is 2/3 of the way full it can hold 2 1/4 cups of fruit

what fraction of the jar is full when it only contains one cup of fruit?

by using these statements , we can solve this through <u>cross multiplication</u>:

fraction that the jar is full : number of cups of fruit

$\frac{2}{3}$ : $2 \frac{1}{4}$

x : 1

$\frac{2}{3} = 2 \frac{1}{4} x$

convert $2 \frac{1}{4}$ from a mixed fraction to an improper fraction

hence 2 1/4 = 9/4

solve

$\frac{2}{3} = \frac{9}{4} x$ .

x = $\frac{2}{3} / \frac{9}{4}$

<h3><u>when the cup contains one cup of fruit its fraction 8/27 full </u></h3>
