             TODAY        YESTERDAY

APPLES       0.9(p+70)       p+70

PEARS        1.2p             p

Total        231


(a)
0.9p%2B0.9%2A70%2B1.2p=231
2.1p=231-0.9%2A70
2.1p=231-63
p=%28231-63%29%2F2.1
p=80
Today he sold 1.2%2A80=highlight%2896%29 pears.

(b)
$ 0.60 for each APPLE
How much money collected for both days just for apples?
