Answer 1

Answer:

373.8 rupees

Explanation:

Given:

initial reading of Ryan's electricity meter = 15863 units

Final reading of Ryan's electricity meter = 15952 units

Rate of 1 unit = Rs. 4.2

To find:

Cost of electricity used by Ryan

No of units used by Ryan in the given week = Final reading of Ryan's electricity meter - initial reading of Ryan's electricity meter

No. of units used by Ryan in the given week = 15952-15863

No. of units used by Ryan in the given week = 89 units

cost of electricity used = 89×4.2

Cost of electricity used = 373.8 rupees

The electricity bill of Ryan is equal to 373.8 rupees
