Can someone tell me the answer? As the number of pounds of apples purchased increases so does the total cost of the apples. If 2.5 pounds of apples cost $7.45, how much does 6 pounds of apples cost?

First divide

6/2.5=2.4

Then multiply

7.45*2.4=17.88

6 pounds of apples cost $17.88

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
