Answer:
a) 45
Step-by-step explanation:
Given:
savings 12% of her salary.
savings $4,200
This year's salary: x + 3,000
Last year's salary: x
4,200 represents 12% of her salary.
4,200 / 12% = 35,000 is her salary this year.
x + 3,000 = 35,000
x = 35,000 - 3,000
x = 32,000 her salary last year.
42%
You have essentially a fraction, 21/50, which gives you a decimal of 0.42, or 42%.
(Flipped a total of 50 times, of those, it landed red side up 21 times, so 21/50)
(-5,0) to make this easier you could use a number line and move to the left 2 places.
