It is not continuous at x=3
The sales tax would be 75 cents i think because .05 x14.90 is 745 and you round to the nearest hundreth so 75 i think i really hope i helped
Senior tickets (x)
Child tickets (y)
First day: 3x + 5y = 70
second day: 12x + 12y = 216
Solve the system of equations (use elimination)
Multiply first equation by -4 -4(3x + 5y = 70), which makes it
-12x - 20y = -280
(+)12x + 12y = 216 add to second equation
-8y = -64
divide by -8. y = 8
Plugin the y value to either equation ( I will choose first equation)
3x + 5(8) =70
3x+ 40 = 70
3x = 30
x = 10
Senior tickets are $10, child tickets are $8
C. 6.25 in
Ratios and cross multiplication:
2 inches is to 130 feet as x is to 406.25 feet
2/130 = x/406.25
(2)(406.25) = (130)(x)
812.50 = 130x
Divide both sides by 130
x = 6.25
