Barnaby decided to count the number of ducks and geese flying south for the winter. On the first day he counted 175 ducks and 63

olga_2 [115]

Answer:

13,125 ducks

Step-by-step explanation:

The ratio of ducks:geese on the first day was:

175:63

On the last day (end of migration), he counted 4,725 geese.

To find the number of ducks using the same ratio, we are first going to divide 4,725 by 63 to find what number all the ducks and geese multiplied by:

4,725/63 = 75

The geese multiplied by 75. This means the ducks also multiplied by 75:

175*75 = 13,125

Barnaby counted 13,125 ducks.

Jayanta is raising money for the? homeless, and discovers each church group requires 2 hr of letter writing and 1 hr of? follow-

boyakko [2]

Answer:

Jayanta needs 2 labor union groups and 8 church groups.

Step-by-step explanation:

Let c denotes churches .

Let l denotes labor unions.

We know that Jayanta can only spend 20 hours letter writing and 14 hour of follow-up.

So, equations becomes:

$2c+2l=20$

$c+3l=14$

And total money raised can be shown by = $150c+175l$

We have to maximize $150c+175l$ keeping in mind that $2c+2l \leq 20$ and $c+3l \leq 14$

We will solve the two equations: $2c+2l=20$ and $c+3l=14$

We get l = 2 and c = 8

And total money raised is $150\times8 + 175\times2$ = $1200+350=1550$ dollars.

Hence, Jayanta needs 2 labor union groups and 8 church groups.
