A store sold 70 hammers and ranchers Hammer sold for $10 each in French so for five dollars each a total of 600.00 what's the co
MrMuchimi

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:

x+y=70...(1)

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:

10x+5y=600...(2)

From equation (1), we will get:

x=70-y

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

700-10y+5y=600

700-5y=600

700-700-5y=600-700

-5y=-100

\frac{-5y}{-5}=\frac{-100}{-5}

y=20

Therefore, 20 wrenches were sold.

Now, we will substitute y=20 in equation (1) as:

x+20=70

x+20-20=70-20

x=50

Therefore, 50 hammers were sold.
