day 3 = 7

day 2 = 7 - 4 = 3

day 1 = 3 * 2 = 6

total seas shells = 7 + 3 + 6 = 16

total money = 16 * 2.45 = $39.20

Find two consecutive odd integers whose sum is 116 (and please have steps) thank you
matrenka [14]
It's 57 and 59
Call (n) is the first odd interger => the second odd interger is (n+2)
=> n + (n + 2) = 116 
=> n + n + 2 = 116 
=> 2n = 114 
=> n = 57 
First odd interger is 57 and the second odd interger is 59 .
