Step-by-step explanation:
What is mean/average?
It is the "sum of all the numbers" divided by the "number of numbers".
An average of 200 for 6 numbers means:
THus, if we were to add the 6 numbers, we would get "1200". Let the 6th number be x, so we can write:
120 + 110 + 200 + 300 + 140 + x = 1200
870 + x = 1200
x = 1200 - 870
x = 330
To make the average $200, Pedro needs to make $330 on 6th day.
Answer:
A
Step-by-step explanation:
The equation y =1, means that y is one for any value of x. Therefore you will get a straight horizontal line that goes through (-1,1) (0,1), (1,1), (2, 1) etc.. It will be parallel to the y-axis, but one unit up, as I have tried to illustrate below:

There is not much that can be done to figure out how to write .15 as a fraction, except to literally use what the decimal portion of your number, the .15, means. Since there are 2 digits in 15, the very last digit is the 100th decimal place. So we can just say that .15 is the same as 15/100.
To change a percent to a decimal we divide by 100. This is the same as moving the decimal point two places to the left. For example, 15% is equivalent to the decimal 0.15. Notice that dividing by 100 moves the decimal point two places to the left.
