The local library has a childern section with pictures books and chapter books the ratio is 2:3 id thete are a total of 500 book

Anvisha [2.4K]

Look at the ratio (2:3). You can see that the numbers of "ratio units" add up to 5, and that the total number of books is 100 times that value. Then each "ratio unit" stands for 100 books.

3 ratio units of chapter books mean there are 300 chapter books.

Alonzo invested his savings in two investment funds. The amount he invested in Fund A was $2000 less than the amount he invested

alina1380 [7]

Answer:

There were $13,200 in Fund B.

Step-by-step explanation:

We are given the following in the question:

Let x be the amount in Fund A and y be the amount in Fund B.

The amount he invested in Fund A was 2000$ less than the amount he invested in Fund B.

Thus, we can write the equation:

$x = y -2000$

Profit percent on Fund A = 7%

Profit percent on Fund B = 8%

Total profit = $1960

Thus, we can write the equation:

$7\%(x) + 8\%(y) = 1960\\7x + 8y = 196000$

Solving the two equations by substitution, we get,

$7(y-2000) + 8y = 196000\\\Rightarrow 15y = 198000\\\Rightarrow y = 13200\\\Rightarrow x = 11200$

Thus, there were $13,200 in Fund B.
