(Context: The JMC's scoring system is as follows: There are 25 questions on the paper, which lasts 1 hour. 5 marks are awarded for each correct answer between Q1-15. 6 marks are awarded for each correct answer between Q16-25) Gill sat the JMC last year, when the scoring system used was the same as this year’s system. She answered all the questions she did correctly. The first question took her 1 second, question 2 took her 2 seconds, question 3 took her 4 seconds and so on, the time doubling for each question. What was Gill’s score?

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

the answer would be 44.79
