Answer:

a)

10 markers : 7 USD

24 markers : 14 USD

42 markers : 21 USD

b)

64 markers : 28 USD

Explanation:

10 markers : 7 USD

24 markers : 14 USD

For 10 markers, the price is 7 USD;

For 14 additional markers, the price increased by 7 USD;

Following the pattern, an additional 18 markers would see the price further increase by 7 USD;

So:

24 + 18 = 42

42 markers : 21 USD

Then, an additional 22 markers would cost 7 USD more than this;

42 + 22 = 64

64 markers : 28 USD
