Answer:
23.7%
Step-by-step explanation:
In order to solve this, we need to find the total expenses as well as the amount of money spent on housing.
The total expenses are simply the sum of the prices of all the items listed under "expenses":
1080 + 385 + 200 + 970 + 230 + 128 + 145 + 210 + 400 + 0 + 410 + 300 + 100 + 0 = $4558
The amount of expenses on housing is $1080. So, divide this by the total and multiply by 100:
(1080 / 4558) * 100 = 23.7%
Remark
You can find the answer to that by dividing any 2 consecutive terms putting the right one in the numerator and the left one in the denominator.
Forumula
ratio = right/left
right = - 8
left = 4
ratio = -8/4
ratio = -2
Any two numbers would work.
ratio = - 32/16 = - 2
