Question 997237
	 Gregory has $6 more than Penny, and Phillip has $13 less than Gregory. How much does each person have if they have $29 altogether?
Please show with working out 
<pre>Let amount Penny has, be P
Then amount Gregory has is: P + 6
Amount Phillip has is: P + 6 - 13, or P - 7
We then get: P + P + 6 + P - 7 = 29
3P - 1 = 29
3P = 30
P, or amount Penny has = {{{30/3}}}, or {{{highlight_green("$"10)}}}
Amount Gregory has: 10 + 6, or {{{highlight_green("$"16)}}}
Amount Phillip has: 10 - 7, or {{{highlight_green("$"3)}}}
