Step-by-step explanation:
The subject of this question is Business and it is appropriate for High School level students. The question involves calculating the linear feet of shelving in a store and comparing sales figures for two quarters. To find the linear feet of shelving, you need to sum up the lengths of all the individual shelves in the store. In this case, the store has 475 linear feet of shelving. To compare the sales figures for the first quarter ($75,000) and second quarter ($86,000), you need to subtract the first quarter sales from the second quarter sales. The increase in sales from the first quarter to the second quarter is $11,000.
