Work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number then this is a percentage decrease.
Answer:
Tauren has 78 keychains
James has 34 keychains
Marcus has 68 keychains
Yahya has 74 keychains
Step-by-step explanation:
I got this answer by doing this:
If Tauren has 78 keychains then its gonna be left like that.
If everybody else has an average of 68 keychains then divide 68 by 2 to get half of what marcus has which equals 34.
Then add the amount of James and marcus keychains which is 68 plus 34 which equals 102, the subtract the 28 because it says Yayha has 28 fewer keychains and that equals 74.

To solve this problem you might have to use this formula y=a(1+r)^t A=amount of money you already have 1= a set number R= rate T= time YOUR GIVENS ARE: A=4000 R= 3.5% (0.035) decimals T= 3 years NOW lets plug IN everything in the FORMULA y=4000(1+.035)^3= $4434.87. NOW lets subtract 4000-4434=434. She earned $434 of simple interest.
