The sport boosters club is having a bake sale to buy uniforms. they want to raise $250. they need to rent a booth for $20. how many dozen cookies will they need to sell if they charge $3 per dozen? which equation could be used to solve this problem

3x - 20 = 250

Step-by-step explanation:

Given,

The cost of cookies per dozen = $ 3,

Let x be the number of dozen cookies sold,

So, the cost of x dozen of cookies = x × cost of cookies per dozen

= 3x

Now, the amount of rent = $ 20,

Thus, total earning = cost of x dozen of cookies - rent

= 3x - 20

If $ 250 is needed to raise,

Then total earning = $ 250

⇒ 3x - 20 = 250

Which is the required equation.

y = x + 95

y = 42 + 95

y=137 mm hg
