The subtotal of a dinner bill is dd dollars. There is an 8% dine-in tax, and the customer would like to leave an 18% gratuity based on the subtotal amount. Write an expression that represents the total amount the customer spends on dinner, including the tax and gratuity.

1.26d

Step-by-step explanation:

Given that :

Subtotal = d

Dime - in tax = 8%

Gratuity = 18% of subtotal

Total amount spent on dinner :

Gratuity = 18% of d

Gratuity = 0.18 * d = 0.18d

Dine - in tax : = 8% of dinner bill

Dine - in tax = 0.08d

Total cost of dinner :

Dinner bill + dine - in tax + Gratuity

d + 0.08d + 0.18d

= 1.26d

Total amount spent on dinner = 1.26d

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )
