The williams family wants to buy these toys. they have $20 bills, $10 bills, $5 bills, and l bills. they want to use the least number of bills to pay for each item which bills will they use to pay for each item? doll cost $18, bicycle cost $83, and basketball cost $49. how can you find the least number of bills to use to pay for any of the 3 items?

The least number of bills you could use for any item is using just 5 to pay for the doll.

Step-by-step explanation:

For any of these, you have to break the number down into its largest parts. Take the doll for examples.

$18 = $10 + $8 = $10 + $5 + $3 = $10 + $5 + $1 + $2 = $10 + $5 + $1 + $1 + $1

Once you have only bill amounts, you can count the number and see how many bills you have to use. Repeat this process for each one.

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!
