The answer is D because the y is the only thing that is changing.
Answer:
7/10
Step-by-step explanation:
Lets set up this word problem as an equation to make it easier to solve.
1/2+2/5 - 1/2 x 2/5
<em>Now lets solve using PEMDAS:</em>
<em />
1/2+2/5 - 1/2 x 2/5 1/2 x 2/5 = 1/5
1/2 + 2/5 - 1/5 1/2 + 2/5 = 9/10
9/10 - 1/5 = 7/10
Divide the interest by the time, then divide that number by the principal. you should get an answer that is 0.0475. or 4.75%
Y=2 by the method of substitution (x is 7).
