Answer:
50 hammers and 20 wrenches.
Step-by-step explanation:
Let x represent number of hammers and y represent number of ranchers.
We have been given that a store sold 70 hammers and ranchers. We can represent this information in an equation as:

We are also told that each hammer sold for $10 and each rancher sold for five dollars resulting a total of 600.00. We can represent this information in an equation as:

From equation (1), we will get:

Substituting this value in equation (2), we will get:






Therefore, 20 wrenches were sold.
Now, we will substitute
in equation (1) as:



Therefore, 50 hammers were sold.
