Myers balloons cost $1.25 each, and latex balloons cost $0.75 each. What equations can be used to find the number of each of bal

fredd [130]

We can use the equations m + n = 18 and 1.25m + 0.75n = 19 to find number of each balloon for Myer

<u>SOLUTION: </u>

Given, Myers balloons cost $1.25 each, and latex balloons cost $0.75 each. We have to find what equations can be used to find the number of each of balloon in a bunch of 18 balloons that costs $19?

Let number of myers balloons be m, and number of latex balloons be n.

Then m + n = 18 ⇒ (1)

And according to given information,

$1.25 x number of myers ballons + $0.75 x number of latex balloons = $19

⇒ 1.25m + 0.75n = 19 ⇒ (2)

Hence, we can use the equations m + n = 18 and 1.25m + 0.75n = 19 to find number of each balloon.

Now, (1) ⇒ m = 18 – n. substitute these values in (2)

(2) ⇒ 1.25(18 – n) + 0.75n = 19

22.5 – 1.25n + 0.75n = 19

1.25n – 0.75n = 22.5 – 19

0.5n = 3.5

n = 7

Then, m = 18 – 7 ⇒ m = 11.

So, 11 myers balloons and 7 latex balloons.

Hannah has to make 25 gallons of punch for a potluck. The punch is made of soda and fruit drink. The cost of the soda is $1.79 p

Rus_ich [418]

Answer:

Hannah needs 10 gallons of soda and 15 gallons of fruit drink

Step-by-step explanation:

Let

x -----> the number of gallons of soda needed

y ----> the number of gallons of fruit drink needed

we know that

$x+y=25$ -----> equation A

$1.79x+2.49y=2.21(25)$

$1.79x+2.49y=55.25$ -----> equation B

Solve the system by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The solution is the point (10,15)

see the attached figure

therefore

Hannah needs 10 gallons of soda and 15 gallons of fruit drink
