Both spent 1u each
Kate after spending->165-u
Cheryl after spending->93-u
After spending Kate 4x of Cheryl
To form equation we multiply 4 to Cheryl values..
4x(93-u)->165-u
372-4u->165-u
3u->372-165=207
u-> 69(ans)

30cups sold
$0.20 x 30 + $10= $16
$112/$16= 7groups of 30 cups
7x30= 210 cups(answer)
Make the amount at first be 35u
(Fractions of denominators 2/5 and 1/7)..
2/5 of 35 u on handphone
Remaining is 3/5 of 35u-> 21u
1/7 of remainder is 1/7 of 21u..
Pls proceed from here...
