Question 1160483
<br>
By standard algebra....<br>
x = # of children
361-x = # of adults<br>
{{{1.50(x)+2.25(361-x) = 632.25}}}<br>
Solve using basic algebra -- although the decimals make the calculations a bit messy.<br>
Alternatively -- but it doesn't simplify the solution process, since the numbers aren't "nice"....<br>
361 people all children would make a total of 361(1.50) = 541.50.
632.25-541.50 = 90.75.
The difference of $90.75 is because of the additional $0.75 per adult.
90.75/.75 = 121.
The number of adults was 121; the number of children was 361-121 = 240.<br>
