Answer:
Natalie saved 16%
Step-by-step explanation:
Natalie saved 16% because 20 divided by 125 is 0.16
When we find percentages our goal is to get something like 0.24 which would mean 24% or 0.14 or 14% in this case it is perfect because we immediately see 0.16 or 16% leaving us with our answer, Natalie got 16% off her new phone.
70a + 55b = 905
a + b = 14
55a + 55b = 770
(70a-55a) + (55b-55b) = 905 - 770
15a = 135
a = 9
a + b = 14
9 + b = 14
b = 5

<span>First, you have to define your x and y axes, what is 0º and what direction do you turn to face 90º.... In algebra, the 0º is the angle from the x-axis, and you turn counter clockwise to get to 90º (the y-axis)
but if you use the compass directions, 0º (north) is the y axis, and you turn CLOCKWISE 90º to get to the x-axis (east)</span>
