Answer:

Amount in 4% account: $550

Step-by-step explanation:

Use simple interest formula $I=P\cdot r\cdot t,$ where

I = interest

P = principal

r = rate (as decimal)

t = time.

4% account:

$P_1=x\\ \\r_1=0.04\\ \\t_1=1,$

then

$I_1=x\cdot 0.04\cdot 1=0.04x$

5% account:

$P_2=1,500-x\\ \\r_2=0.05\\ \\t_2=1,$

then

$I_2=(1,500-x)\cdot 0.05\cdot 1=0.05(1,500-x)$

You have earned $69.50 in total, so

$I_1+I_2=69.50\\ \\0.04x+0.05(1,500-x)=69.50\\ \\4x+5(1,500-x)=6,950\\ \\4x+7,500-5x=6,950\\ \\4x-5x=6,950-7,500\\ \\-x=-550\\ \\x=550\\ \\1,500-x=1,500-550=950$

Amount in 4% account: $550

Amount in 5% account: $950

What is the simplified form of the equation 4/5n - 3/5 = 1/5n?

Oksi-84 [34.3K]

Answer:

n = 1 if you meant "(4/5)n - (3/5) = (1/5)n"

Step-by-step explanation:

There's some ambiguity here. Did you mean (4/5)n or did you

mean --------- ? Please use parentheses to eliminate this ambiguity.

I'm going to assume that you meant to type in (4/5)n - (3/5) = (1/5)n.

Then we have (3/5)n = 3/5, or n = 1
