You open a checking account. you are paid 3% interest on the average daily balance, but are charged a $4 monthly charge. assuming that interest is paid monthly (regardless of the number of days in the month), calculate the average balance you must maintain to offset the $4 monthly charge.

x=4

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
