At Carl's Cambie Diner, there are three sizes of coffee drinks: regular (300 mL), large (500 mL) and extra large (800 mL), and they cost $2.25, $3.25 and $5.75, respectively. On a particular afternoon, the diner sold a total of 37 coffees. the total volume of coffee sold was 19,100 ml and the amount of money made in coffee sales was 133.25. How many of each size of drinks did customers buy that afternoon

is there any attachment? what are the equations?

what are the answer choices given for this problem?

hi there

the slope is 1/3.

this is because from the y-intercept, you go up one, and you go to the right three, to get to the next exact point on the graph. this is known at the “rise over run.”

p.s. (if you need it).your y-intercept is -2, because that is the point on the graph where the line crosses the y-axis.

hope that : )
