Hi, need help to solev this Qs:-

Q18 : There were lilies and roses in a shop.
The ratio of the number of lilies to the number of roses was 13:10.
After 30% of the lilies and 1/5 of the roses were sold, there were 22 more lilies than roses left.

(a) How many lilies were there in the shop at first?
(b) A florist bought all the remaining lilies for \$45.50. How much did she pay for each lily?

Many thanks!

Please refer to my attachment before viewing the workings.

a) 11u---> 22
1u-----> 2
130u-->260

b) 91u---> 182
\$45.50/182 = \$0.25

I hope this helps you.

Hi tchtby,

Thanks for the detailed drawing and workings. Now I am able to see the question clearly.

Would be thankful if you could help solve the other school questions that I posted. Getting nervous as exams draw near.

Many thanks
