Answer:
$9000
Step-by-step explanation:
Let a and b represent the amounts invested in the two funds. The problem statement gives two relations:
a = 2b . . . . . . the amount invested in A was twice that invested in B
7%×a +3%×b = 1530 . . . . . the total profit from the two funds
Substituting for a in the second equation, we have ...
0.07(2b) + 0.03b = 1530
0.17b = 1530 . . . . . . . . . . collect terms
1530/0.17 = b = 9000
Deandre invested $9000 in Fund B.
Answer:
<em>Question 3. Option B,</em>
<em>Question 4. Option D,</em>
<em>Question 5. Option B</em>
Step-by-step explanation:
Question 3.
If we have a table, we can note that each juice has a proportionality among one another - comparative to the number of servings. If we can figure out this proportionality, we can apply it to the servings of grapefruit juice;
As we can tell, this " proportion " is 1 to 2. Thus, the amount of grapefruit for 16 servings is 2 * 3 = 6c -<em> Option B</em>
Question 4.
The distance Carlos biked is 24 miles, the total distance he covered is 30 miles;

4.95 = 100% of the price
100 less 35 = 65
4.95 X .65% = 3.2175 or 3.22
