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

i think that you should ask google for the answer to that problem because if we don't know it google does
