To determine how many glasses Max and Leah sold after 5 hours, we can calculate the sales for each person individually.
Max:
- In the first hour, Max sold 12 glasses.
- In the next 4 hours, he sold 10 glasses each hour.
- So, in the first hour: \(12\) glasses.
- In the next 4 hours: \(4 \times 10 = 40\) glasses.
- Total sold by Max after 5 hours: \(12 + 40 = 52\) glasses.
Leah:
- Leah sold "a" glasses in the first hour and then 10 glasses each hour after that.
- In the first hour, Leah sold \(a\) glasses.
- In the next 4 hours: \(4 \times 10 = 40\) glasses.
- Total sold by Leah after 5 hours: \(a + 40\) glasses.
To compare the totals, we need Leah's initial sales "a." However, the options provided suggest values for Leah's total sales.
Given the answer options: A) Max 52 glasses, Leah 48 glasses B) Max 50 glasses, Leah 50 glasses C) Max 60 glasses, Leah 40 glasses D) Max 52 glasses, Leah 48 glasses
From our calculation, Max has sold 52 glasses.
For Leah:
- To have sold 48 glasses in total: \(a + 40 = 48\) implies \(a = 8\).
- Therefore, Leah sold 8 glasses in the first hour.
So the answer, with Max selling 52 glasses and Leah selling 48 glasses, corresponds to option A: Max 52 glasses, Leah 48 glasses.
