Answer:
215 senior citizens tickets
Step-by-step explanation:
Senior citizens tickets x Numbers
Adult ticket s ------------ y Numbers
x+y=325 .............1
7x+9y=2495.............2
Eliminate y
multiply (1)by -9
Multiply (2) by 1
-9x-9y=-2925
7x+9y=2495
Add the two equations
-2x = -430
/-2
x=215 Senior citizens tickets
The answer to your question is adults = 68 seniors 271
Data
Adults = a = $14
Seniors = s = $10
total people = 339
total earnings = $3662
number of adults = ?
number of seniors = ?
Process
1.- Write two equations to solve this problem
a + s = 339
14 a + 10s = 3662
2.- Solve by substitution
a = 339 - s
14(339 - s) + 10s = 3662
4746 - 14s + 10 s = 3662
Solve for s
-14s + 10 s = -4746 + 3662
-4s = - 1084
s = 1084/4
s = 271
3.- Find a
a + 271 = 339
a = 339 - 271
a = 68
Something like M=80-(7x4)
y=mx + b
the slope is -3,2
y= -0.67x + 5
this is what. i got i could be wrong, sorry if i am
