The absolute value of a number is the distance it is from 0. The bug is currently to the left of 0 and the absolute value of its location is 4. Where on the number line is it?

- 4

Step-by-step explanation:

The absolute value of a number renders a number positive regardless of the preceeding sign. Therefore, either a number is positive or negative, the absolute value of such number will be positive.

In a number line, 0 is the midpoint and values to the left of 0 are negative, while those to the right are positive.

For the scenario, above, the bug is to the left of 0 and has an absolute value of 4 ;

The current position of the number line will be 4 (absolute value) places to the left of 0 which is - 4 (negative numbers are in the left).

32.94 + 15.89 + 2(19.99) = 88.81
88.81 * 0.07 = 6.2167
88.81 + 6.21 = 95.02
Lunch:
6.95 + 1.49 + 3.49 = 11.93
11.93 * 0.07 = 0.83
11.93 + 0.8351 = 12.76
Tip with tax -->
12.76 * 0.15 = 1.91
12.76 + 1.91 = 14.67

Total: 95.02 + 14.67 = 109.69
(p.s. The total would be different if Teri gave the tip to the server pre-tax)
