Because the earnings are $21 when Marsha sells 6 frozen yogurts, a constant of proportionality for this situation is c. or 3.5. So, an equation for the relationship is y = 3.5x. d. Use the equation y = 3.5x to find the number of yogurts Marsha has to sell. Substitute 245 for y in the equation. 245 = 3.5x 245 3.5 = x 70 = x Marsha would have to sell 70 yogurts to raise $245 for the library. 25. ANS: C LOC: MAFS.7.RP.1.3 26.
