Answer 1

Answer:

Inequality:$0.25x\geq 145$

Answer: At least 580 cookies

Step-by-step 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:

$0.25x\geq 145$
