Answer: 18 and 32
Step-by-step explanation: The first thing you want to do is create a system of equations.
Let's use x to represent one number and y to represent the other.
So, we know that x+y=50 and x-y=14.
We can manipulate the second equation, making it x=y+14 by adding y to both sides. Then, now that we have an equivalent to x, we can plug it into the first equation to solve for y.
(y+14)+y=50
2y+14=50
2y=36
y=18
x+18=50
x=50-18
x=32
x=32, y=18
Answer:
USD $342.47
Step-by-step explanation:
For these kinds of questions, I like to use what I call the 'I want... If' method. I'll walk you through my thought process. Essentially, when I write my formula, I think, 'I want to find out how many US dollars I can receive from JMD $50,000 if JMD $146 is USD $1.
Essentially, the 'I want to find out... $50,000' part goes in the nominator of a fraction. 'If JMD $146' goes in the denominator of the same fraction. Then, add a multiply operator and finally 'is USD $1' goes after the operator.
In working, it looks like this:
JMD $ x USD $1 = USD $342.4657534247 = USD $342.47 (To 3 s.f.)
