Joe needs to buy supplies for a birthday party. at the store, balloons cost $0.50 each and party hats each cost $1.25. if joe wants to spend exactly $20 on the party supplies, which equation below represents the number of balloons ( b) and the number of party hats ( h) that he can buy?

The equation is:

0.50 b+ 1.25 h= 20

Step-by-step explanation:

Let 'b' denotes the number of balloons.

and 'h' denote the number of party hats.

Also we are given that:

Cost of 1 balloon= $ 0.50

and Cost of 1 party hat= $ 1.25

Now it is given that Joe wants to spend exactly $20 on the party supplies, that means that the total amount he spends on the balloon plus the amount he spends on party hat is equal to $ 20.

so, we can write the equation of this condition as:

0.50 b+ 1.25 h= 20

Hence, equation that represents the number of balloons ( b) and the number of party hats ( h) that he can buy is:

0.50 b+ 1.25 h= 20

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
