Question

Jason has four dollars more than Robert while Nancy has triple Roberts money how much do they each have is some of their money totals to $67

Answer 1

r = 12.6, j = 16.6, n = 37.8

Explanation:

Set up your system of equations:

j = 4 +r

n = 3r

67 = j + n + r

Plug in the first two to get down to just r so that you can solve:

67 = (4 + r) + 3r + r

67 = 5r + 4

63 = 5r

12.6 = r

Plug in r value into the other two equations above to get j and n:

j = 4 + 12.6 = 16.6

n = 3(12.6) = 37.8

Hope this helps!
