460= 40+ 12x
X equal the cost per month, which is what we're looking for.
460=40 +12x
-40 -40
420=12x
420/12= 35
So they would pay $35 per month with the $40 fee, as seen in the $460 fee.
Answer: House = 550 and Porch = 325
Explanation:
Porch = (30 x 15) - [(30 + 20)5/2]
Porch = 450 - 125
Porch = 325
House = (30 x 10) + 2(125)
House = 300 + 250 = 550
So first, we want to find the total decrease on the number.
Since it was first decreased by 50% and then 10%, we can just multiply the two together to find what 10% of 50% is. I find it easier when they're both fractions, or 1/2 and 1/10.
1/2 * 1/10 = 1/20
So one quarter is 1/4, or 5/20.
1/20 is 4/20 less then 5/20.
1/20 is 30 less then 1/4, then 4/20 must equal 30.
4/20 is also 1/5.
So just multiply 30 by 5, to get 150 as your number. (1/5 * 5 = 5/5)
