Mrs. Eraca gives this cute dog 4.5 treats that cost $3.59 per treat. How much total money does she spend on this mooching pooch? Round answer to the nearest penny! (Show all work)

$16.16

Step-by-step explanation:

multiply the amount of treats by the cost of each treat.

4.5 × 3.59 = 16.155.

rounded up gives you $16.16

1 = 3.59

2= 7.18

3= 10.77

4= 14.36

half or .5 of 3.59 is 1.795

14.36 + 1.795 = 16.155 = rounded up $16.16

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
