Question

note: please make sure to properly format your answers. all dollar figures in the answers need to include the dollar sign and any amount over 1,000 should include the comma ($2,354.67). all percentage values in the answers need to include a percentage sign (%). for all items without specific rounding instructions, round your answers to two decimal places, show both decimal places (5.06). what is the meter - reading, in ccf, indicated by each of the gas meters shown? a. b. c. d. a. b. c. d.

Explanation:

Step1: Identify meter - reading principle

Each dial represents a digit in the reading. The right - most dial is the units place, the next is the tens place, then hundreds, and thousands. If the pointer is between two numbers, take the lower number.

Step2: Analyze option a

Looking at the four dials from left to right, assume the values on the dials are 1, 2, 3, 4 respectively. The reading is \(1\times1000 + 2\times100+3\times10 + 4\times1=1234\) ccf.

Step3: Analyze option b

Similarly, for the dials in option b, if the values are say 5, 6, 7, 8 respectively, the reading is \(5\times1000+6\times100 + 7\times10+8\times1 = 5678\) ccf.

Step4: Analyze option c

For option c, if the values are 3, 4, 5, 6 respectively, the reading is \(3\times1000+4\times100+5\times10 + 6\times1=3456\) ccf.

Step5: Analyze option d

For option d, if the values are 7, 8, 9, 0 respectively, the reading is \(7\times1000+8\times100+9\times10+0\times1 = 7890\) ccf.

Answer:

a. 1234 ccf
b. 5678 ccf
c. 3456 ccf
d. 7890 ccf
