Write as an equation: mike, carroll, and jim, empty their wallets and have $175 total. mike has three times
as much as carroll. carroll has twice as much money as jim. how much money does each have?
a. j +2j +3j = 175
b. 3j+2(3 + j) = 175
c. j +2j + 3(2j) = 175
d. 7j = 175

  C.  j +2j + 3(2j) = 175

Step-by-step explanation:

Let j represent the amount of money Jim has.

Carroll has twice that amount, so has 2j.

Mike has 3 times the amount Carroll has, so has 3(2j).

The sum of these quantities is 175, so the equation can be written ...

  j + 2j + 3(2j) = 175 . . . . . matches choice C

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

answer: the answer is 110
