Answer:
n = d+30 since he has 30 more nickels than dimes, to make them equal you have to add 30 to the dimes.
:
n+d = 150 substitute for n:
d+30+d = 150
2d = 120
d = 60 he has 60 dimes and 150-60 = 90 nickels
To answer the question, let x be the number of adults going to the zoo and 2x be the number of children. The total amount gained from the ticket sales should be,
1650 = 6x + 4(2x)
The values of x is equal to 117.86. Therefore, the school bought approximately 118 tickets for adults and 236 for children.
Wouldn't this be in literature?
