Question

A toy factory creates handmade train sets. One train car takes 0.4 hours to construct and 0.6 hours to paint. A section of wooden track requires 0.2 hours to construct and 0.1 hours to paint. A full train set with x train cars and y sections of wooden track takes 5.2 hours to construct and 4.2 hours to paint. Which system of equations can be used to find the number of train cars and number of sections of wooden track in a full train set?

Answer 1

X = train cars, y = tracks

0.4x + 0.2y = 5.2.....this one deals with the constructing
0.6x + 0.1y = 4.2 ....this one deals with the painting
