The rate to rent a small moving van is $30.00 per day, plus $0.50 per mile. jada rented a van to drive to her new home. it took two days, and the van cost $360.00 total. how many miles did jada drive?

So Jada for 1 day, gets charged $30 flat
now, she drove 2 days, so...she's charged 2 * 30 or 60 bucks
plus the mileage

is 0.5 per mile so... 1 mile is 0.5
2  miles 2 * 0.5
3 miles 3 * 0.5
4 miles 4 * 0.5
5 miles 5 * 0.5
x miles x * 0.5

she drove "x" miles, whatever that is
we also know, her total cost in the end, was 360
so... those 360 include the 2 days charge, 30 * 2
plus the mileage,  x * 0.5 or 0.5x
so... one can say that

360 = (30 * 2) + 0.5x    < solve for "x"
