<h3>
Answer: C) 75% increase</h3>
===========================================================
Explanation:
We go up by 300,000 since 700,000-400,000 = 300,000
Divide this increase by the original amount
(300,000)/(400,000) = 0.75 = 75%
Therefore, we have a 75% increase.
It might help to ignore the zeros and just think of it like this: "We start at 4 and jump to 7. That's an increase of 3, so we have a 3/4 = 0.75 = 75% increase".
Answer:
a equals and b equals 7
Step-by-step explanation
divide both side by 3 getting a+b=(28/3)
subtract b from both sides getting a=(28/3)-b
to solve for b its the same way so b=(28/3)-a
you can then substitute
Answer:
Lisa earned $247.50 for working 33 hours.
Step-by-step explanation:
WAY 1: proportional reasoning
7.50 x
------ = ----
1 h 33h
33 / 1 = 33
7.50 x 33 = 247.5
WAY 2: unit rate reasoning
7.50 per hour so x value of money for 33 h
7.50 x 33 = 247.5
