Sarah is selling cookies and brownies to raise money for her school trip. She needs to raise at least $350. She is selling cookies for $1 and brownies for $2. Let x represent the number of cookies and y represent the number of brownies. Write an inequality to represent how many cookies and brownies Sarah would have to sell to have enough money for her trip?

Since cookies are $1 each --- $1x
Brownies are $2 each ----- 2y
And she needs at least $350 means she can make either more that 350 or exactly 350 hence the inequality will be
x + 2y ≥ 350

The inequality that represents how many brownies and cookies that Sarah would have to sell to have enough money for the trip is: x + 2y ≥ 350

Recall:

Inequality can be used to represent a real life situation. It involves inequality sign, variables and numbers.

Thus, we are given the following:

x = number of cookies
y = number of brownies
Cost of 1 brownies = $2
Cost of 1 cookies = $1
Minimum amount she needs to raise = $350

Therefore, the inequality that represents how many brownies and cookies that Sarah would have to sell to have enough money for the trip is: x + 2y ≥ 350
