let her morning walk distance be x

her evening distance walk =2 1/2 x

her daily walk distance =5x/2+x

her weekly walk distace= 7x/2*7=49x/2=30miles

x= (30*2)/49

A group of adults and students went on a class trip to Washington, DC. The number of male students was 1 more than 7 times the n
liberstina [14]
Given:
adults = x
male = 7x + 1
female = (7x + 1)/2
total number of people = 82

x + (7x + 1) + [(7x +1)/2] = 82
2x/2 + (14x + 2)/2 + (7x + 1)/2 = 82
2x + 14x + 2 + 7x + 1 = 82 * 2
23x + 3 = 164
23x = 164 - 3
23x = 161
x = 161/23
x = 7

adults = x = 7
males = 7x + 1 = 7(7) + 1 = 49 + 1 = 50
females = (7x+1)/2 = 50/2 = 25

7 + 50 + 25 = 82

18 - 4.25 = 13.75.
13.75 - 9.75 = what is left to spend, $4.00

This means she can buy no more than 8 cracker packs.
