The number of tomatoes Reggie bought in September was 40% more than in August. In October, he bought 75% less tomatoes than in September. If there were 91 more tomatoes in August than October, how many tomatoes did Reggie buy in August?

100% + 40 = 140%

75September : August = 7 : 5
100% - 75% = 25%
25% =
25100 =
14 October : September = 1 : 4
The number of tomatoes in September is repeated. Make the number of tomatoes in September is the same. LCM of 7 and 4 is 28.
Number of more tomatoes in August than October
= 20 u - 7 u
= 13 u
13 u = 91
1 u = 91 ÷ 13 = 7
Number of tomatoes that Reggie bought in August
= 20 u
= 20 x 7
= 140
Answer(s): 140
