Answer:
y=10x+50
Explanation:
The line starts at point (0,50) which is the y intercept (how much he gets paid to visit house).The line crosses points (10,150) and (20,250) and the slope of these points are 100/10 which when simplified equals 10x which is how much money he gets paid by the hour(x=hours) so y=10x plus the y intercept y=10x+50
Answer:
a+c=27
195a+320c=6515
Step-by-step explanation:
adult (a): 195
children (c): 320
total $: $6515
child $: 27
a+c=27 --> c=-a+27
195a+320c=6515
sub the first equation into the 2nd equation to get a=17
sub a=17 into c=-a+27 to get c=10
so, an adult ticket is $17 and a child ticket is $10.
