First , we need to apply the distributive property.

0.15*n - 0.15*250 =

0.15n - 37.5 + 5

-37.5 + 5 = -32.5

Final answer: 0.15n - 32.5

ExtremeBDS [4]

Complete Question:

Here is the complete question:

<em>A lumber yard has five different lengths of 2 by 4 boards. Based on cost per linear foot, which is the best deal available on 2 by 4 boards at this lumber yard?</em>

<em>2 × 4 BOARD PRICES </em>

<em>8 foot board for $2.95 </em>

<em>10 foot board for $3.15 </em>

<em>12 foot board for $4.10 </em>

<em>16 foot board for $5.80 </em>

<em>20 foot board for $6.95</em>

Step-by-step explanation:

  • 8 foot board for $2.95

         \frac{2.95}{8}= 0.36875

  • 10 foot board for $3.15

        \:\frac{3.15}{10}=0.315

  • 12 foot board for $4.10

        \frac{4.1}{12}=0.341

  • 16 foot board for $5.80

        \frac{5.8}{16}= 0.3625

  • 20 foot board for $6.95

        \frac{6.95}{20}= 0.3475

Therefore, <em>10 foot board for $3.15</em><em>  </em>is the best deal available on 2 by 4 boards at this lumber yard. It means  you should be able to get 1 board for $0.315 when you buy 10 boards.
