Pedro wants to walk from the historic village to the science center. Then he will walk from the science center to the museum. If he walks at a speed of 3 3/8 miles per hour, how long will it take him?

ratio is 2 : 9

the answer is three

13.5 : 3

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
