Answer:
$69.60
Step-by-step explanation:
20% of $58 is $11.60. So you add $11.60 + 58 which equals $69.60, so that is the total cost.
The desired amount (total cost) is equivalent to the sum of the bill and 20% of the bill, or, equivalently, 120% of the bill.
1.20($58) = $69.60
The total cost is $69.60, including a 20% tip.
6 * (5 + n)
Explanation:
Sum = addition
Difference = subtraction
Product = multiplication
Quotient = division
y = 2x + 54
slope of equation:
(y2-y1)/(x2-x1)
= (72-58)/(9-2)
= 14/7
= 2
y = 2x + b
58 = 2(2) + b
58 = 4 + b
b = 54
