Step-by-step explanation:

you are a very nice person for helping your mom. good luck for this!

ok let's work on question 7 first.

$63.99 is the cost of a skateboard.

15% of 63.99 = 10% + 5%

10% of 63.99 = 6.399 (move the decimal one place to the left)

5% of 63.99 = 1/2 of 6.399

1/2 x 6.399 = 3.1995

6.399 + 3.1995 = 9.5985

ok, so that's 15% of 63.99

now we need to take away 9.5985 from 63.99

63.99 - 9.5985 = 54.3915

the discount price of the skateboard is $54.3915

a further 10% is $5.43915

so take off that from the discount,

54.3915 - 5.43915 = 48.95235

the final price is $48.95235

QUESTION 8

shop A = 6.95 x 40

6.95 x 40 = $278

shop B = 20% of 325

20/100 * 325 = 65

325 - 65 = 260

therefore, shop B is cheaper.

hope this helped, good luck!

225 serves because you need to set up a proportion. The proportion is 2/5=90/x then solve for x by cross multiplying, which gives you 450=2x. Then divide 450 by 2 which gives you 225. Work shown in the attached picture.
