If john ate 1/2 on Friday, then there was a full half of pizza left when he finished.
And if he ate 1/3 of what was left on Saturday, there was only 2/3 of the pizza left for him to eat. So he ate 2/3 of a pizza on Sunday
Let f and t be the number of fives and tens respectively...
f+t=138
f=138-t and we are told that:
5f+10t=1015, using f from above in this equation gives you:
5(138-t)+10t=1015
690-5t+10t=1015
690+5t=1015
5t=325
t=65 and since f=138-t,
f=73 so
Alice has 73 fives and 65 tens.
