Answer:

<em>The man paid $200 for the cow</em>

Step-by-step explanation:

<u>System of Equations</u>

Let's call:

x = price of the cow

y = price of the horse

The man bought the cow and the horse for $500, thus

x + y = 500        [1]

The cow was sold at a profit of 10%, thus:

Sale price of the cow= 1.1x

The horse was sold at a loss of 10%, thus:

Sale price of the horse= 0.9y

The total operation was a 2% loss, i.e. 0.98*500=490. Thus, we have:

1.1x + 0.9y = 490        [2]

From [1]:

y = 500 - x

Substituting in [2]:

1.1x + 0.9(500 - x) = 490

Operating:

1.1x + 450 - 0.9x = 490

0.2x = 490 - 450 = 40

x = 40/0.2

x = 200

The man paid $200 for the cow

Which statement is true?
Nataliya [291]

Answer:

D

Step-by-step explanation:

We can see in the graph f(x) that the x intercept is (1,0).

In the table of g(x), we can see that the x intercept is (-1,0).

Since 1>-1, the x intercept of the graph f(x) is greater than the x intercept of graph g(x).
