C. She paid $3 for each packet of a dozen ballons. She sold each new packet of 25 for $10 each. How much money did she make?

Answer 1

Kelvin, this has many steps, but we can do it!

 

First, let's add 49 + 66 + 35 = 150 packs of balloons.

 

Each pack has 12 balloons, so 150 x 12 = 1800 balloons.

 

If she repacks them into packets of 25, we divide 1800 ÷ 25 = 72 

 

If she gives away 225 balloons, then 225 ÷ 25 = 9 packets given away.  72 - 9 = 63 packets left.

 

If she paid $3 for each original packet, then 150 x $3 = $450.

 

She sold the 63 packets (after giving 9 away) for $10.  63 x $10 = $630.

 

$630 - $450 = $180 in profit.

 

Hope this helps!
