Javier had $305 in his bank account. His bank charges a fee of $7.50 each month that a balance is below $500. If he makes no other deposits or withdrawals, how much money is in Javier’s account at the end of three months? Write an equation and solve.

$282.5

Step-by-step explanation:

$7.50 * 3= $22.5

$22.5 is the total money that is charged from Javier's bank account.

Subtracting that from his $305, we get:

$305 - $22.5 = $282.5

Therefore, Javier has $282.5 in his bank account at the end of three months.

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
