A store is having a sale on jellybeans and trail mix. For 8 pounds of jellybeans and 3 pounds of trail mix the total cost $34. For 2 pounds of jellybeans and 5 pounds of trail mix the total cost is $17. Find the cost of each pound of jellybeans and each pound of trail mix.

Cost of jellybeans = x = $3.5

Cost of trail mix = y = $2

Step-by-step explanation:

Let

Cost of jellybeans = x

Cost of trail mix = y

8x + 3y = 34 (1)

2x + 5y = 17 (2)

Multiply (1) by 5 and (2) by 3

40x + 15y = 170 (3)

6x + 15y = 51 (4)

Subtract (4) from (3)

40x - 6x = 170 - 51

34x = 119

x = 119/34

x = 3.5

Substitute x = 3.5 into (1)

8x + 3y = 34

8(3.5) + 3y = 34

28 + 3y = 34

3y = 34 - 28

3y = 6

y = 6/3

y = 2

Cost of jellybeans = x = $3.5

Cost of trail mix = y = $2

step-by-step explanation:

what are the statements? and what do you mean by "216 2 1 6"?

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
