The first one should be $105.44 and the second one should be $105.35. this is right because the phrase "1-4, stay on the floor" and "5-9, climb the vine" is a useful tip for rounding!

Please help me to find the answer Y=2X 3X+4Y=22 Y=2X 3X+4Y=22

RSB [31]

<h3>System of equations.</h3>

$\left\{\begin{array}{ccc}y=2x&(1)\\3x+4y=22&(2)\end{array}\right$

Put (1) to (2):

$3x+4(2x)=22\\3x+8x=22\\11x=22\qquad|\text{divide both sides by 11}\\\boxed{x=2}$

Substitute the value of x to (1):

$y=2\cdot2\\\boxed{y=4}$

Solution:

$\huge\boxed{\left\{\begin{array}{ccc}x=2\\y=4\end{array}\right}$

Terry deposits $200 into a bank account that earns 3% simple interest per year. What is the total amount in the account after 2

MrRa [10]

Well first you have to solve for the 1st year so 200*.03, .03 represents the 3%. Which would equal 6 dollars so after the 1st year he would have 200+6=206.

Now you do the second year so do 206*.03, which would equal 6.18 so 206+6.18=212.18

Answer= 212.18
