Answer: B, $78
Step-by-step explanation:
If the tip is 20% of the dinner cost, then we have to first find what is 20% of 65.
20% x 65 = 13. So the tip for the dinner is 13 dollars.
Now we have to add it to the original dinner cost.
65 + 13 = 78.
Therefore, the total cost of their meal is 78 dollars. So the answer is B, $78!

Answer:
She can't buy all that with 275, she needs at least 278. But she pays about 17 dollars in tax. original answer without rounding would be $16.97.
Step-by-step explanation:
Jeans are 42 dollars, she buys 3, that costs $126.
Shirts cost 27 dollars, and she buys 5, that'll cost her $135.
total price without sales tax is $261.
multiply 261 by .065 (percent as a decimal) and you end up with 16.965, round that off to be a correct number in money terms and you get $16.97.
Add 16.97 to 261, and what do you know, she doesn't have enough money to buy it all. Poor Tiffany
<h2>
Question:</h2>
A surveyor is estimating the distance across a river. The actual distance is 284.5 m. The surveyor's estimate is 300 m. Find the absolute error and the percent error of the surveyor's estimate. If necessary, round your answers to the nearest tenth.
<h2>
Answer:</h2>
(i) Absolute error = 15.5m
(ii) Percent error = 5.5%
<h2>
Step-by-step explanation:</h2>
<em>Given:</em>
Actual measurement of the distance = 284.5 m
Estimated measurement of the distance by the surveyor = 300 m
(i) The absolute error is the magnitude of the difference between the estimated value measured by the surveyor and the actual value of the distance across the river.
i.e
Absolute error = | estimated value - actual value |
Absolute error = | 300m - 284.5m | = 15.5m
(ii) The percent error (% error) is given by the ratio of the absolute error to the actual value then multiplied by 100%. i.e
% error = x 100%
% error = x 100%
% error = 0.05448 x 100%
% error = 5.448%
% error = 5.5% [to the nearest tenth]
