A) 1.15m dollars

B)
(x)/(30) = 15%/100% (cross multiply)


(100x)/(100) =(450)/(100)

x=$4.40

$30.00+4.50

=S34.50

These are correct answers because I using Math in Focus Singapore Math by Marshall Cavendish (Grade 7). The back page has answers about your question. :)

The expression would be: m + 0.15m and to know how much she paid I believe it would be 26.09 (rounded)


Hope it helped!
