Answer:
More unknown than equations, the answer cannot be determined
Step-by-step explanation:
We can solve by means of a 2x2 system of equations, we have to:
"x" is the number of children's tickets
"y" is the number of adult tickets
Thus:
blank * x + 8.75 * y = 259
x + y = 35
which means that the number of children in the group cannot be calculated with the supplied data, this is because we have 3 unknowns and there are 2 equations, which means that the system has no solution.
If we assume a value, for example, $ 5
We can solve:
5 * x + 8.75 * y = 259
x + y = 35 => x = 35 - y
replacing we have:
5 * (35 - y) + 8.75 * y = 259
175 - 5 * y + 8.75 * y = 259
- 5 * y + 8.75 * y = 259 - 175
3.75 * y = 84
y = -84 / 3.75
y = 22.4
Thus:
x = 35 - (22.4) = 12.6
there being then 22 adults and 13 children.
