exis [7]

Answer:

93/481

Step-by-step explanation:

<u>Total number of integers from 300 through 780, inclusive:</u>

780 - 299 = 481

Tens - 5*10 = 50 (31th, 41th, 51th, 61th, 71th)
Units - 4*9 + 7 = 43 (300 till 699 and 700 till 780)
So in total 50 + 43 = 93

Sholpan [36]

Answer: 10.53%

Step-by-step explanation:

George £89400 @ 9% = £8046 so income = £89400+£8046=£97446

Harris (Paris?) gets £447 more so 97446+447=£97893

and this represents sales of £89400 plus commission

so Harris' commission = £97893-£89400 = £8493

So last stage is what commission percentage is £8493 of original sales £89400 = 10.53%
