1000feet/5feet= 200feet
The answer would be 25
9 times 2 is 18 plus 7 is 25
14 of the machine that cost $150 was sold and 8 of the machine that cost $225 was sold.
To solve this problem, we would write a system of linear equations.
- Let x represent the machine that cost $150
- Let y represent the machine that cost $225
We can proceed to write our equations now.

From equation 1

<h3>The Value of Y</h3>
put equation (iii) into (ii)

<h3>The Value of X</h3>
Since we know the number of y, we can simply substitute it into equation (i) and solve.

From the calculations above, 14 of the machine that cost $150 was sold and 8 of the machine that cost $255 was sold.
