Answer:

t = 1.5 = 1 ½ years

Explanation:

I = Prt

I is the interest in money, P is the principle in money, r is the rate, and t is the time in years

Given I = $174, P = $1450, and r = 8%.

Rearrange the formula so that t is being solved for:

I = Prt → I / Pr = Prt / Pr → I / Pr = t →

t = I / Pr.

Then substitute:

t = I / Pr → t = (174) / (1450)(8%) →

(174) / (1450)(0.08)

x% = x / 100.

(174) / (1450)(0.08) → 174 / 116 → 87 / 58 → 87 ÷ 29 / 58 ÷ 29 → 3/2.

3/2 = 1.5 = 1 ½.

William has $12.80 in coins to be deposited in the bank. There are 3 times as many quarters as nickels and 20 more dimes than ni
Natali5045456 [20]

Let the number of nickels be = n

Let the number of dimes be = d

Let the number of quarter be = q

Total money William has = $12.80

As given, there are 3 times as many quarters as nickels

q=3n

And 20 more dimes than nickels

d=20+n

As total money is $12.80

0.05n+0.10d+0.25q=12.80

Putting the values of 'q' and 'd' to find 'n'

0.05n+0.10(20+n)+0.25(3n)=12.80

0.05n+2+0.10n+0.75n=12.80

0.90n+2=12.80

0.90n=10.80

n=12

Hence the number of nickels are = 12

If you want to also find dime and quarter, then

q=3n=3\times12=36

d=20+n=20+12=32
