Abaker made 81 onion bagels one morning. the onion bagels were 45% of the bagels she made. how many bagels did the baker make? use the percent formula to solve the problem. latex: \frac{\%}{100}\: =\: \frac{part\: \left(is\right)}{whole\: \left(of\right)}

180 bagels total

Step-by-step explanation:

Let  b represent the total number of bagels made.  Then 0.45b = 81, and b = 81/0.45, or 180 bagels total.  Note that that "45%" must be converted into the decimal fraction 0.45 here.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
