Tan's electricity bill for the month of august was $267.00. his september bill showed a 2% increase from his august bill. in october, his bill deacreased by 8% from the amount he was billed in august. how much did tan spend on electricity over the three-month period?

Start by getting what a 1% depression would be:

267,000 / 100 = 2,670 (this is 1%)

In September, his cost increases 2%:

267,000 + 2 * 2,670 = 272,340

In October, the cost decreased by 8%:

267,000 - 8 * 2,670 = 245640

Add the three months up:

267,000 + 272,340 + 245,640 = $784,980

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.
