brainiest answer

machine that cost £35,000 is operated 8 hours a day in a 5-day week but one hour each day is used for test purposes. for use of the machine there are three scales of charges, the first at the rate of £5 an hour for private use, the second at £15 an hour for research work and the third at £40 an hour for commercial work. it is estimated that the number of hours charged at the first, second and third rates are in ratios 4: 2: 1. what percentage of total receipts do receipts from commercial work represent?

a.44.5
b.24.5
c.34.5
d.55.5

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
