Question 1207183
This sentence is troubling:
The price of all the chocolates to the price of all the lollipops was in the ratio of 5 to 2. 


One might have to assume you really mean, "cost" and not "price".
<pre>
                   PRICE(cents)     AMOUNT          COSTS

CHOCOLATES          5y/(7x)           7x             5y

LOLLIPOPS           2y/(4x)           4x             2y

DIFFERENCE           15
</pre>
One useful equation would be  {{{(5y)/(7x)-y/(2x)=15}}}


Maybe want to change the form using {{{14x}}};


{{{10y-7y=210x}}}


{{{3y=210x}}}


{{{y=70x}}}--------------Can you find some whole numbered solution?  More than one solution, as whole numbers?


Something still seems off here.
