Final answer:
The student's question involves setting up an inequality to represent the profits from selling peach and berry smoothies and solving to find the number of each needed to exceed $90 in profit.
Step-by-step explanation:
The student's question relates to a business mathematics problem where a cafe sells two types of smoothies with different profits and wishes to make a total profit of more than $90 per day. To determine how many of each smoothie the cafe needs to sell to exceed $90 in profits, we can set up a system of equations or inequalities with variables representing the number of peach and berry smoothies sold. For example, if we let p be the number of peach smoothies and b be the number berry smoothies, the inequality for the total profit per day would be 2.25p + 2b > 90. This inequality can be solved through various algebraic methods, such as graphing or using the substitution or elimination methods, to find combinations of p and b that satisfy the condition for the desired profit.
To calculate the total profit needed to exceed $90, we can use the inequality: 2.25x + 2y > 90, where x represents the number of peach smoothies sold and y represents the number of berry smoothies sold. The cafe owner should find the combination of peach and berry smoothie sales that satisfies this inequality and helps achieve the desired profit.
