Jennifer earned = $48

x=80

Hence total earnings are $80

(a) Chris earning is =

Hence, Chris earns $32

(b) Jennifer spends 30% of her earnings on a book.

Money left with Jennifer = 48-19.80= $28.20

In fractions =

or multiplying the numerator and denominator by 10, we get

=

(d) Let the original price of the shirt = x

reduction percentage on x= 40%

Price paid after reduction = 16.80

Hence, the original price of the shirt was $42.

answer is:
