Alocal restaurant, a couple ordered two dinners for $12.50 each and two drinks for $1.50 each. if the couple left an 18% tip, what was the total cost of the meal? a $16.52 b $25.15 c $28.18 d $33.04

The total cost of the meal was $33.04.

Step-by-step explanation:

A local restaurant, a couple ordered two dinners = $12.50 each

They ordered two drinks = $1.50 each

Total bill for two dinners and two drinks = 2 (12.50) + 2 (1.50) = $28.00

The couple left a tip of 18% of the bill = 18% of 28.00

= × 28.00

= 0.18 × 28.00 = $5.04

The total cost of the meal =  28.00 + 5.04 = $33.04

The total cost of the meal was $33.04.

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
