Answer:

Let x = the number

"Fifteen more than" means addition

"Three times a number" is multiplication

"three less than" is subtraction, as is the term difference

Putting it all together, we have

7 - (15 + 3x) = (9 - 5x) - 3

-8 + 3x = 6 - 5x

-8 = 6 - 8x

-14 = -8x

14/8 = 7/4 = x

Calculate the total budget and then fill in the missing percentages (to the nearest tenth). Item $ % Contributions $175.76 Housi

Alik [6]

Answer:

Total Budget = 1,116

Contributions = 175.76/1,116 = 15.8%

Housing = 350.84/1,116 = 31.4%

Transportation = 50/1,116 = 4.5%

Clothing = 30/1,116 = 2.7%

Medical expenses = 35/1,116 = 3.1%

Food = 200/1,116 = 17.9%

Taxes = 106.40/1,116 = 9.5%

Miscellaneous = 168/1,116 = 15.1%

Step-by-step explanation:

Let's calculate the total budget and the percentages (to the nearest tenth).

Total Budget = 175.76 + 350.84 + 50 + 30 + 35 + 200 + 106.40 + 168

Total Budget = 1,116

Contributions = 175.76/1,116 = 15.8%

Housing = 350.84/1,116 = 31.4%

Transportation = 50/1,116 = 4.5%

Clothing = 30/1,116 = 2.7%

Medical expenses = 35/1,116 = 2.7%

Food = 200/1,116 = 17.9%

Taxes = 106.40/1,116 = 9.5%

Miscellaneous = 168/1,116 = 15.1%
