The equation to relate weight w to the price p is: [tex]p = 0.45w[/tex]
Given data from the table is:
- w = 3.8 pounds, p = $1.71
- w = 5.2 pounds, p = $2.34
Formation of equation:
[tex]\text{3 pound of \$1.31 price}\\\text{1 pound} = \$\dfrac{1.31}{3} = \$0.45 \: \rm price[/tex]
Thus, w pound of weight will cost:
[tex]w \times 1 \: \rm pound \: \rm in \: \: \$0.45 \times w \: \: \rm price[/tex]
Thus, w pound of weight will cost $0.45w price.
This fact can be converted to equation as:
price of w weight = p = 0.45w (in dollars)
Thus, the equation to relate weight w to the price p is: [tex]p = 0.45w[/tex]
