Your interest formula is given to you.
<span>Interest in a year = principal (the amount invested) * rate (the interest rate) * period (the time you're measuring) </span>
<span>Interest = 55,000 * 2% * 1 year = 55,000 * 0.02 * 1 = $1,100 </span>
<span>How much would you need to have made for your spending power to keep with inflation? Your interest rate would have needed to match the inflation rate, otherwise, prices are going up faster than you're saving. </span>
<span>Required interest = 55,000 * 3.24% * 1 year = 55,000 * 0.0324 * 1 = $1,782 </span>
<span>How much buying power did you lose? The difference between your required interest and your actual interest. </span>
<span>Buying power lost = 1,782 - 1,100 = $682. You lost this much in buying power. </span>
Answer:
y = 6
x = 200
Quick Explanation:
The horizontal arrowed line labeled <em>t</em> would be the <em>y </em>axis, and according to the dot on the graph, it's on the 6. The vertical arrowed line labeled <em>h </em>would be the <em>x </em>axis, and the dot tells you the number is 200. Easy peasy, just remember the <em>x </em>axis is vertical and the <em>y</em> axis is horizontal and it'll help you find the location of any dot.
9(3j-6) = 27j - 54

Rounds to 240
So average rate is 240
To simplify <span>2x + 8 = -6, the easiest way is to manipulate the equation one step at a time:
</span>2x + 8 = <span>-6
</span>2x = <span>-14 (subtract 8 from both sides)
</span>x = -7 (divide both sides by 2)
