C= number of acres of corn
W= number of acres of wheat
total is 180 acres
c+w=180
want to plant 3 times as many corn as wheat
c=3w
substitute 3w for c in other
ctw=180
3w+w=180
4w=180
divide both sides by 4
subtract
c=3w
c=3(45)
c=135
135 acres of corn and 45 acres of wheat

Answer:
25.95 quarters which is about 6.5 years
Step-by-step explanation:
Theres roughly 53 weeks in a year (rounded up) that times two would be 106 weeks, take that times 15 and you would have 1,590 dollars (again this was rounded up if your looking for exact it would be wrong)
it would of course be much closer to 1,564 if it wasn't rounded
