1. Percent error is 
The guess is 15.5mi, and the actual distance is 14.5 mi.
Percent error is
2. The cost will be $31.95*(1+0.075) = $34.35
The 1 represents 100% of the original amount of $31.95, and now we add 7.5% (0.075) to the 100%. In other words we multiply $31.95 by 107.5%.
3. His commission will be $165 out of $4125, or $165/$4215 = 0.039 = 3.9%
4. The principal (amount of money you start with) is $12000, and the interest rate is 15% of that.
15% of $1800 = 0.15*$12000 = $1800

49/60 - 3/20 = (49 - 3(3))/60 = (49 - 9)/60 = 40/60 = 4/6 = 2/3
Answer:
2/3
Answer:
17
Step-by-step explanation:
Look at any 2 adjacent numbers and find the difference between them.
Starting with numbers 1 and 2, subtract the first from the second:
That's a difference of 8, meaning the second number increased by 8.
Check the next numbers, 2 and 3:
It increased by 8 again. Now that we know for sure that each term in the sequence increases by 8 over the previous one, we can find the number in the green box. Just add 8 to the number before it:
