I believe it is d also hope that help
first you would multiply 25 x 3, which is 75 and then multiply 60 x 2 which is 120, then add 120 and 75 together, making the answer 195
Two straight lines perpendicular to each other, the slope of which is negative reciprocal.
y=-4/3x+b
The known points are put into the linear equation
y=-4+b
b=13
y=-4/3x+13
C = child tickets
a= adult tickets
c + a = 157
6.20c + 9.30a = 1178.00
6.20c + 9.30a = 1178.00
-6.20c -6.20a = -973.40
3.10a = 204.60
a = 66 adult tickets
c + 66 = 157
-66. -66
c= 91 child tickets
