Joylin is writing an equation to model the proportional relationship between y, the total cost in dollars of downloading videos from a website, and x, the number of videos downloaded. She knows that the total cost to download 3 videos was $12. Her work to find the equation is shown below. Joylin’s Work Step 1 k = StartFraction 3 over 12 EndFraction = 0.25 Step 2 y = 0.25 x Where did Joylin make her first error Joylin divided 3 and 12 instead of multiplying the two numbers. Joylin computed the decimal equivalent of StartFraction 3 over 12 EndFraction incorrectly. Joylin used 0.25 as the coefficient of x instead of a product of x and y. Joylin switched the numerator and the denominator when she found k.
