Answer:
The total cost of the meal including tip is $55.80.
Step-by-step explanation:
Cost of the meal = $46.50
tip = 20%
total cost = ?
Finding the tip cost:
20% of cost of the meal is equal to the tip cost.
20% of 46.50
(% = 1/100 and of means multiplication)
20/100 * 46.50
930/100
$9.30
20% tip = $9.30
Finding total cost:
Cost of the meal + tip
46.50 + 9.30
55.80
The total cost of the meal including tip is $55.80.
Width = W
Length = 12W - 1
Perimeter = 2L + 2W = 37
In the perimeter equation substitute the length equation in for L to get the equation in terms of W
2L + 2W = 37
2(12W - 1) + 2w = 37
Distribute
2(12W - 1) + 2w = 37
24W - 2 + 2w = 37
26W = 39
W = 3/2 = 1.5
Width = 1.5
Lastly, solve for length
L = 12W - 1
L = (12 • 1.5) - 1
L = 18 - 1
L = 17
Length = 17
