Answer:
Step-by-step explanation:
Let x represent the amount on deposit at 12%. Then 5900-x is the amount deposited at 6%, and the total interest earned is ...
12%·x +6%·(5900 -x) = 540
0.06x + 354 = 540 . . . . . . . . eliminate parentheses
0.06x = 186 . . . . . . . . . . . . . . subtract 354
x = 3100 . . . . . . . . . . . . . . . . . divide by 0.06
Scott invested $3100 at 12% and $2800 at 6%.

<em>Quick sanity check</em>
The average interest earned is $540/$5900 ≈ 0.0915 ≈ 9.15%. This is more than the average of 12% and 6%, which is (12+6)/2 = 9 percent. Hence more than half of the money must be deposited at 12%.
Answer:
20 mins
Step-by-step explanation:
The distrance to be travelled is 8/10 - 2/25 therefore:
Total dlistance = 81/10 - 12/5
add using least common denominator:
Total distance = 81 - 12 x 2
10
evaluate: Total distance = 57/10 = 5.7
according to the given information if they travel at a speed of 3 miles per house and there are 12-10= 2 hours, so the distance travelled to noon will be 2x = 6 miles - 5.7 miles. This implies that they will be able to reach the 8 1/10 mark by noon.
