Bill spent 70 on fertilizer and weed killer for his lawn .each pound of fertilizer cost 50 cents and each once of weed killer cost 3.50 . write an equation that correctly represent this relationship if x represents the number of pounds of fertilizer and y the number of ouncescof weed killer

An equation that correctly represent this relationship if x represents the number of pounds of fertilizer and y the number of ounces of weed killer is  0.5x + 3.5y = 70

Solution:

Given that, Bill spent 70 on fertilizer and weed killer for his lawn

Each pound of fertilizer cost 50 cents and each once of weed killer cost 3.50

We have to write an equation, if x represents the number of pounds of fertilizer and y the number of ounces of weed killer.

Now, total amount = amount for fertilizers + amount for weed killers.

Total amount = number of pounds of fertilizers x cost per pound + number of ounces of weed killer x cost per ounce.

Hence, the equation is 0.5x + 3.5y = 70
