Question 1186268
---------------------------------------------------
Mary spent 0.7 of her money on 15 mangoes
and 5 oranges, if each orange cost half as much
as a mango, how many oranges could she buy
with the rest of her money?
---------------------------------------------------


M amount of money

n, price of 1 Orange
2n, price of 1 mango


{{{0.7M=15*2n+5n}}}
{{{0.7M=35n}}}
{{{M=35n/0.7}}}
{{{M=50n}}}


{{{n=M/50}}}------------price of 1 orange
{{{M/25}}}--------------price for 1 mango
{{{0.3M}}}--------------amount of money Mary has after the first described purchase.


The question:
Amount of oranges she can buy using the remaining 0.3M of money:
{{{0.3M*(1/(M/50))}}}
{{{0.3*50}}}
