Answer:

$29,005.97

Step-by-step explanation:

Cn = Co * (1 + i)^n

Cn = 104,986.99(1+.05/1)^(1*5)

Cn = 104,986.99(1+.05)^5

Cn = 104,986.99(105)^5

Cn = 104,986.99(1.2763)

Cn = 133,992.96, total money at end

133,992.96-104,986.99= $29,005.97, interest accumulated

There are 870 boys and 800 girls in a school

alina1380 [7]

Answer:

1060

Step-by-step explanation:

Given:

No. of boys = 870

No. of girls = 800

Probability that a boy chosen studies Spanish = $\dfrac{2}{3}$

Probability that a girl chosen studies Spanish = $\dfrac{3}{5}$

the number of boys in the school who study Spanish :

$\dfrac{2}{3}\times 870=290\times 2=580$

the number of girls in the school who study Spanish :

$\dfrac{3}{5}\times 800 \\=3\times 160\\\\=480$

Therefore, total number of students who study Spanish would be :

480+580=1060
