A3pack of boxes of juice costs 1.09. a 12 pack of boxes cost 4.49. a case of 24 boxes costs 8.78. which is the best buy? explain your reasoning

1.09÷3= .3633 each
4.49÷12= .37416 each
8.78÷24= .3658 each

so the first one

Im sorry but what on

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
