15 pounds of peanuts cost 45 dollars
how much does 1 pound of peanuts cost
ok

15 times (cost per pound)=45
represent cost per pound with 'w'
15 times w=45
15w=45
divide both sides by 15
w=45/15
w=3
cost is $3 per pound

The Robinson family bikes on a 15 mile trail going one way only. In the end, they have biked a total of 45 miles. Write an equation and solve to find how many people are in the Robinson family. 
15w=45
w=45/15
w=3
Hope this helps.
