Hannah drove 36 miles and needs to dive 24 more miles
"hi" drove 50 miles and "hi" has to drive 10 more miles
"hi" drove further than hannah by 14 miles
<span>Let the amount invested at 4% be $100X
THEN , the amount invested at 5% WILL BE $200X
Interest earned = 4X + 10X = 266
14X = 266
X = 19 </span>
Think about it this way: which numbers are perfect squares? The square root of 4 is two, the square root of 49 is 7, and the square root of 64 is 8. That only leaves B.
I hope this helps. Let me know if you need a further explanation.
The correct answer is: [A]: " x = 3 " .
