Doritos' logo is shown to the right. They plan to take the triangular part of the logo shown to the right and enlarge it to fit on a shirt they are using as a promotional give- away. The triangle currently has lengths of 6cm ( side on the left closets to the "D", 4cm (bottom), and 5cm (side on top right). To fit the shirt, they need the side on the left to have a length of 18cm. a) Set up the proportions

b) Solve for the missing two lengths for the t- shirt design.

  a) 18/6 = b/4 = r/5

  b) b = 12, r = 15

Step-by-step explanation:

a) The proportion will simply state the fact that the ratio of shirt dimension to logo dimension is the same for all. We'll use 'b' for the bottom dimension and 'r' for the upper right dimension. Then the proportions are ...

  shirt/logo = 18/6 = b/4 = r/5

b) In each case, multiply by the denominator to find the value of the variable.

  3(4) = b = 12

  3(5) = r = 15

The bottom dimension is 12 cm; the top right dimension is 15 cm.
