7400 dollars is placed in an account with an annual interest

Anastasy [175]

Answer:

Step-by-step explanation:

We have the following equation for compounding annual interest

AV=PV(1+i)ⁿ

We have

19200=7400(1+.06)ⁿ

Solve for n

divide both sides by 7400

2.594=(1.06)ⁿ

then use the following rule for exponents

$x^y=z\\log_xz=y$

which means that

$log_{1.06}2.594=n$

Solve and get

16.362

which rounds to 17

How many pounds of a 4% solution of borax must be added to 24 pounds of a

Marrrta [24]

Answer:

8 pounds of 4% solution of borax

Step-by-step explanation:

Let x be the 4% solution

24 pounds of 12% solution

obtain a 10% solution of borax that is (x+24) pounds

4% is 0.04 and 12% is 0.12 , 10% is 0.1

$0.04x+24(.12)=0.1(x+24)$

solve the equation for x

$0.04x+24(.12)=0.1(x+24)\\0.04x+2.88= 0.1x+2.4\\2.88= 0.06x+2.4\\0.48=0.06x\\x=8$

so 8 pounds of 4% solution of borax
