Answer:

No, It is not equal to a 60% discount.

Step-by-step explanation:

Think of this. I go into a store and everything is 50% off and I have a coupon myself that is a 50% off discount for a specific item. It may seem like the item is now free, but it isn't. Imagine the item was $1 before any discount. Then the store took 50% off of the $1, leaving it at $0.50. So now with my discount of 50% off the item I will be taking this 50% off of $0.50 = my final discounted cost of $0.25.

Hope I helped you understand :)

I'll give a practice problem to help explain it a bit better.

Here, let's try to solve 45% of of 60.

First, we convert the percentage into a decimal. To turn any percentage into a decimal you move the point two spaces to the left.

That means 45% as a decimal is .45.

Next, we multiply our number, 60, by the decimal .45.

60×.45=27.

That means 45% of 60 is 27.

To sum it all up, you have to get the percentage, move the decimal point two spaces to the left, and multiply it by the number you were trying to find the percentage of.

Have a wonderful day! :)

Which linear function represent the table?​
rodikova [14]

Answer:

Step-by-step explanation:So, if the graph is a straight line, it is the graph of a linear function. From a table, you can verify a linear function by examining the x and y values. The rate of change for y with respect to x remains constant for a linear function. This rate of change is called the slope.Mar 9, 2011

I mean 125.06 in fraction form is 6253/50, if that works great.

125.06 million dollars, if you can use the number in the question.
