Tonisha has a lemonade stand. She has $36 in expenses and wants to make at least $55 per day if represents the amount of revenue from selling lemonade, an inequality to represent the amount of revenue she would need to generate would be:

Step-by-step explanation:x  is the total amount of money earned. You subtract 36 from x because that's the amount of her expenses. The answer has to be either equal to or greater than 55 since she wants to make at least $55 per day.  

x - 36 ≥ 55

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74
