While on vacation in rockport, cole went out for a dinner that cost $30. if sales tax in rockport is 10% and cole left a 20% tip on $30, what was the total cost of his meal?

$39

Step-by-step explanation:

To calculate the total cost of his meal, add the subtotal ($30), the tax on subtotal ($30 X 10%) and the tip ($30 X 20%).

Convert all percentages to decimals to multiply.

Finding tax:

10% = 0.1

Tax = $30 X 0.1 = $3

Finding tip:

20% = 0.2

Tip = $30 X 0.2 = $6

Subtotal + Tax + Tip

= $30 + $3 + $6

= $39

The total cost of his meal was $39.

rounding to the nearest thousandth would be 452,000

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
