Cost of each balloon is $1.89

Step-by-step explanation:

Given Josh had $150 to spend on 75 balloons for the birthday party. After buying the balloons, Josh had $8.25 left. we have to find the cost of each balloon.

Let the cost of 1 balloon is $x

Since, Money left after buying 75 balloons is $8.25 and the total money Josh had is $150.

∴ The equation can be written as

(Cost of 75 balloons) + Money left=Total money

⇒ 75x+8.25=150

⇒ 75x=150-8.25=141.75

⇒ x=1.89

Hence, cost of each balloon is $1.89
