Amoving van rents for $29.95 a day plus $.12/mi. mmi. ms smiths bill for a two day rental was $70.46. how many miles did she drive

She drove 88 miles

Step-by-step explanation:

Total cost =  fee per day + cost per mile * miles driven

We know the total cost was 70.46

The  fee per day  was 29.95 *2 =59.90.  She kept the van 2 days.  

The cost per mile was .12

Substitute in what we know

70.46 = 59.90 +.12 m

Subtract 59.90 from each side

70.46-59.90 = 59.90-59.90 +.12 m  where m is the miles driven

10.56 = .12m

Divide each side by .12

10.56/.12 = .12m/.12

88=m

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!
