6 days
Y= 107-8x
Y=83-4x
You can use substitution
83-4X= 107-8x
Bring 8X
Over to the left
83+ 4x=107

Subtract 83
4x= 24
X=6
Or put in calculator and go 2nd graph you see table and on 6 day they both have $59

Jack looks at a clock tower from a distance and determines that the angle of elevation of the top of the tower is 40°. John, who
Margaret [11]

tan(40) = (y + 1.5) / (x + 20)

y + 1.5 = (x + 20)[tan(40)]

y = (x + 20)[tan(40)] - 1.5

tan(60) = (y + 1.5) / x

y + 1.5 = (x)[tan(60)]

y = (x)[tan(60)] - 1.5

(x)[tan(60)] - 1.5 = (x + 20)[tan(40)] - 1.5

(x)[tan(60)] = (x + 20)[tan(40)]

(x)[tan(60)] = (x)[tan(40)] + (20)[tan(40)]

(x)[tan(60)] - (x)[tan(40)] = (20)[tan(40)]

(x)[tan(60) - tan(40)] = (20)[tan(40)]

x = [(20)(tan(40))] / [tan(60) - tan(40)]

x = 18.8 meters
