sarah has a job at a salon and she earns $50 per day plus tips. her average tip is 15% of the total amount her customers spend on services.

sarah's daily income is represented by the variable y and the amount her customers spend is represented by the variable x.

which equation represents sarah's daily income?

y = 0.5x + 15

y = 50x + 15

y = 15x + 50

y = 0.15x + 50

she makes 50 per day so that would be the constant number

 o you have y = 50 + something

her tips are 15% , which is 0.15x

so her pay would be y = 0.15x +50

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
