Question

The MRA volleyball team decides to raise some extra money for their trip by horganizing a cookie sale. The cost to make the cookies is $45 and the team is charging $0.25 a cookie. How many cookies must be sold to make a profit of at least $100? write an inequality.​

Answer 1

Inequality:
`0.25x\geq 145`

Answer: At least 580 cookies

Explanation:

Lets say they sell x cookies.

Now, that means they will make 0.25x as their income(the price multiplied by the number of cookies).

We know that totally they need to make 100+45 dollars, because that is what will give them a $100 profit. So they need to make $145

Now just set 0.25x equal to $145.

`0.25x=145`, and now solve

`x=145*4`

`x=580`

For an inequality, we could just say that:

`0.25x\geq 145`
