Randi and her sister make balloon animals and sold them for $.50 each. They made $48.00. If rando made twice as many animals as
nydimaria [60]

Randy made 64 ballon animals and her sister made 32 ballon animals

<em><u>Solution:</u></em>

Let the number of ballon animals sold by Randi be "x"

Let the number of ballon animals sold by her sister be "y"

Cost of 1 ballon animal = $ 0.50

<em><u>Rando made twice as many animals as her sister</u></em>

Number of ballon animals sold by Randi = twice the number of ballon animals sold by her sister

x = 2y ---- eqn 1

<em><u>Together, they earned $ 48</u></em>

Therefore, we can frame a equation as:

Number of ballon animals sold by Randi x Cost of 1 ballon animal + number of ballon animals sold by her sister x Cost of 1 ballon animal = 48

2y \times 0.50 + y \times 0.50 = 48

1y + 0.5y = 48\\\\1.5y = 48\\\\y = \frac{48}{1.5}\\\\y = 32

<em><u>Therefore, from eqn 1</u></em>

x = 2y

x = 2(32)

x = 64

Thus Randy made 64 ballon animals and her sister made 32 ballon animals
