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"
Answer:
(3,2)
Step-by-step explanation:
2x+3y=12
substitute x with 3 because x=3
2(3)+3y=12
multiply
6+3y=12
(subtract 6 from both sides)
3y=6
(divide by 3 on both sides)
1y=2
x = 3 and y = 2
