##### 1 Answer

The cost would be

#### Explanation:

Let

In March the cost was

#$175 = 1500x + y" "# and#" "$225 = 2300x + y#

Solve each for

#y = $175 - 1500x" "# and#" " y = $225 - 2300x#

Since

#$175 - 1500x = $225 - 2300x#

Add

#$175 + 800x = $225#

Subtract

#800x = $50#

Divide both sides by

#x = $0.0625#

Putting this back into the equation,
