Amount that Flynn received from selling of
14 of the large avocados = 6 u
6 u = 90
1 u = 90 ÷ 6 = 15
Number of medium avocados at first
= 8 u
= 8 x 15
= 120
(b)
Amount that Flynn collected more from selling the medium avocados than the small avocados
= 40 u - 4 u
= 36 u
= 36 x 15
= $540
Answer(s): (a) 120; (b) $540
