Answer:
$85.60
Step-by-step explanation:
In this question, we need to find the price of the calculator after tax.
We know the cost of the calculator is $80 and the sales tax is 7%
To find your answer, we would multiply 80 by 1.07:
80 · 1.07 = 85.60
The total cost of the calculator is $85.60
Answer: B?
Step-by-step explanation:
Answer:
By scoring 240 in the sixth game, Marlon can maintain this exact average
Step-by-step explanation:
The first thing to do here is to calculate the average for the first 5 games.
Mathematically, the average can be calculated by adding all the scores in the games and dividing by 5;
= (210 + 225 + 254 + 231 + 280)/5 = 1200/5 = 240
Now to maintain this average score of 240, we want to know the score she must have in the 6th game.
Let the score be x;
By adding x to the previous total of 1200 before and dividing by the new count of 6, we can work our way to get x.
Mathematically, what we are saying is;
(1200 + x)/6 = 240
6 * 240 = 1200 + x
1440 = 1200 + x
x = 1440 -1200
x = 240
The answer is b because if you look there is no Direct variation
If 2 stands for 2 out of 10 (2/10); Then the answer is 20%.
