There needs to be values to answer the question.
A=adult ticket s=student ticket
64a+132s=$1040
a=2s
128a+132s=$1040
260tickets=$1040
$1040/260=$4
s=$4 (1s=$4x1)
a=$8 (2s=$4x2)
132s=$528 (132x$4)
64a=$512 (64x$8)
TOTAL=$1040
Rida:
5 1/2 :77
5.5 : 77
Divide both sides by 5.5 to get $/hour:
1:14
Elisa:
3 3/4:60
3.75:60
Divide both sides by 3.75 to get $/hour:
1:16
16 is bigger than 14 so Elisa earns more.
The sum of d anf f can be expressed as:
