Sarah went up an escalator, then took the stairs back down. graph time on the x-axis, then distance traveled on the y-axis .

answer:

220

step-by-step explanation:

    220

step-by-step explanation:

the x and y value as according to the information are as follows:

        x (number of weeks)         y(amount of cans collected)

                  0                                         20

                  1                                           40

                  2                                         60

                  3                                         80

                  4                                         100

hence, we see that with each increasing weeks the number of cans collected increased by a constant rate i.e. 20

the equation that represent these points are:

                      y=20(x+1)

now we have to calculate the value of y when x=10

when x=10 we have:

          y=20(10+1)

          y=20×11

          y=220

hence, the answer is:   220

x+14
