Mr Lee has 185 more chicken pies than tuna pies. After he sold 3/5 of the chicken pies and half of the tuna pies there were 146 pies left. How many pies were sold?
5 C - 2 T --> 185
2 C + 1 T --> 146
4 C + 2 T --> 2 x 146 = 292
9 C --> 292 + 185 = 477
1 C --> 477 ÷ 9 = 53
1 T --> 146 - 2 x 53 = 40
3 C --> 3 x 53 = 159
159 + 40 = 199
It was 199 pies.
