Hi belnanna,

One possible solution:


Roy → $675


Yvonne → (0.8 × $675)
[Yvonne had 20% less than Roy]


Sufen → (0.8 × $675) ÷ 1.35 = ??
[Yvonne had 35% more money than Sufen]


Can you solve from here?

Please let us know if you still need help.

Hi,
Can someone help with the following question ?



Thanks in advance!

If each girl gets 3 rubber bands,

170 - 5 x 3 = 155

155/7 = not whole number (reject)


If each girl gets 6 rubber bands,

170 - 5 x 3 x 2 = = 140

140/7 = 20

20/2 = 10

10 x 7 = 70 boys

70 : 5 = 14 : 1

a) The ratio of boys to girls is 14 : 1


70 + 5 = 75 girls and boys

b) There are 75 girls and boys.
