A triangular tower is built with 11 rows as shown. Each square on the bottom row contains the number 0 or 1. Each square above the bottom row is the sum of the two squares below it. A student insists on the number in the top square being a multiple of 3. How many ways are there entering the 0s and 1s in the bottom row to satisfy the student?

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
