For 13. the answer is w = -1.
Here are the steps
1. subtract 5 from both sides ( 3w = 2 - 5)
2. simplify 2 - 5 to -3 (3w = -3)
3. divide both sides by 3 ( finally the answer is w = -1.
)
You need to know the difference in change between .40 and 7.25, which is 6.85, then you divide the change in price by the original amount, so you do 6.85/.40, which is 17.125, then multiply by 100 to get percent and you get 1712.5% increase.
