P = -------------
2 - r
Step-by-step explanation:
Solve for P: P(2-r)-17=109
Combining the constant terms:
P(2 - r) = 126
Dividing both sides by (2 - r) isolates P:
126
P = -------------
2 - r
Answer:10 10 = 100
Step-by-step explanation:
count to 10 10 times
To convert a percentage to a decimal we divide it by 100. So, 5% = .05
To find the tax, multiply the cost by the tax rate
(.05)(11.20) = 0.56
Add this to the cost to get the total
$11.20 + $0.56 = $11.76
