Six rolls of paper towels cost 7.80 what is the cost of the eight rolls?

the answer is 10.40

Step-by-step explanation:

7.80 / 6= 1.3

1.3 x 8= 10.4

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
