mehek14 · Answer

x = y + 4
0.99x + 1.29y = 15.36

mehek14 · Answer

0.99x + 1.29y = 15.36
0.99(y+4)+ 1.29y= 15.36

mehek14 · Answer

0.99y + 3.96 + 1.29y =  15.36
2.28y + 3.96= 15.36

solve for y
2.28y + 3.96= 15.36
2.28y = 11.40
y = 5

so sorry.. my computer started acting weird so I rebooted. Thank you for your help!  It is for my daughter...I am helping her with her review for a final and I am NOT  good with word probs. If I can get it set up then I can figure it out....but not good with setting it up. I love that you gave step by step instructions...that makes it easier for me to explain to her. Thanks again!
