Amount that Elijah received from selling of
13 of the large peaches = 8 u
8 u = 152
1 u = 152 ÷ 8 = 19
Number of medium peaches at first
= 15 u
= 15 x 19
= 285
(b)
Amount that Elijah collected more from selling the medium peaches than the small peaches
= 90 u - 3 u
= 87 u
= 87 x 19
= $1653
Answer(s): (a) 285; (b) $1653
