Kapil needed to buy a long wooden beam. He went to two sawmills that each charge an initial fee plus an additional fee for each
matrenka [14]

Answer: first sawmill charges more for each meter of wood. And first mill has a cheaper price for 5-meter wooden beam.

Step-by-step explanation:

P=5+20x. The first sawmill charges $20. Then 110-20/5-0=18 Which means The second sawmill charges $18 for each meter of wood. Since 20>18 The first sawmill charges more for each meter of wood.

P = 5+20x

=5+20x•5

= 105

The first mill charges $105 For a 5 meter beam while the second beam charges $110
