you and your friends collect toys for toy drive you collected 20 more toys than Julian Betty collected for more toys as you if you all collected 280 toys how many toys did each person collect

Answer 1

j =y-20 = 260

b = y+4

sum = y+j+b = 280

y + y-20 +y+4 = 3y -16 = 280

3y = 296

y = 98 2/3

b = 102 2/3

j = 78 2/3

the fractional number of toys per person suggests a problem with the problem

probably mis-copied or misprinted

Answer 2

Hello Cathy,

The big picture of this question is that we have three variables

x = you.

y = Julian

z = Betty

Now given the parameters of the problem we substitute in to each of the variable equations

x = 20 + y EQ 1

z = 4 + x EQ 2

x + y + z = 280 EQ 3

now we have three equations of three unknowns and are gonna solve for x y and z

substitute equation one into equation 2, and get

z=4 +20 + y

z = 24 + y

substitute equation one for x into EQ 3

20 + y + y + z = 280

2y + z = 260

substitute z = 24 + y into 2y + z = 260 and get

2y + 24+ y=260

3y=236

y=78.67

Substitute this equation one and solve for x

X = 20 + 78.67 = 98.67

Now take the values for x and y and substitute into equation 3 and solve for Z

98.67 + 78.67 + z = 280

z = 102.66

those are the answers for x, y, and z

Seems different that they all have fractional pieces
