1. Correct option is A. For x<= 6 will the total cost of buying the materials and renting the tools.

   In terms of the number of days, x, from shop A, the total price, y, for purchasing the goods and renting the tools is –

   y=750+(15+65)x,

   y=750+80x.

   Similar to this, the total cost y for purchasing the supplies and renting the tools from store B is

   y=600+(25+80)x,

   y=60+105x.

   Given that purchasing goods and renting equipment from store B will cost less overall or the same as purchasing materials and renting tools from store A.

   ⇒ 60+105x ≤ 750+80x.

   ⇒ 105x−80x≤750−60

   ⇒ 25x≤150

   ⇒x≤6

   Complete question –

   Mr. Martinson is building a concrete patio in his

   backyard and deciding where to buy the materials and

   rent the tools needed for the project. The table below

   shows the materials’ cost and daily rental costs for three

   different stores.

   The total cost, $y,$ for buying the materials and renting the

   tools in terms of the number of days, $x,$ is given by

   $y=M+(W+K) x$

   For what number of days, $x,$ will the total cost of

   buying the materials and renting the tools from

   Store B be less than or equal to the total cost of

   buying the materials and renting the tools from

   Store $A$ ?
