The contestants total number of points is 20.
30 + 15 = 45
45 - 25 = 20 total points
If the one for $175 is 10% off, that means Fiana pays 90% of the price
175 * 0.9 = $157.50
It is too expensive because 157.50 is more than the 150 Fiana has.
The second bike for $225 is 35% off which means Fiana pays 65% of the price.
225 * 0.65 = $146.25
She CAN afford the bike for $225
3/7. if you make them equivalent fractions it would be 30/70 or 14/70. 30/70 is bigger.
Moving left subtracts from the x value the number you move.
In (2,9) the x value is the number 2
You move 1 unit to the left so subtract 1 from 2:
2-1 = 1
You will be at (1,9)
Where the points intersect should be the solution to systems of equations.
