Answer:

The cost of a candy bar is $0.75.

Step-by-step explanation:

With the provided first sentence preceded along the lines, 'total cost of a candy bar and a bag of chips is $1.70.'

--Intially, determine the quotient of 1.70 and the two quantities.

+ Result should be 0.85

Thus symbolizing .85 is the valid price of a candy bar and a bag of chips.

------------------------- Although, we are not done. -----------------------------------

Let's take the second sentence into account.

"If the cost of a candy bar and 2 bags of chips is $2.45, what is the cost of a candy bar?"

Determine the sum of .75 and (.85*2)

Alert: .75 came from subtracting 10 from the intial .85

Thus the sum is $2.45, which was stated earlier as the cost of a candy bar and 2 bags of chips.

Anna35 [415]

Answer:

The amount of interest earned at the end of 14 years would be $672.3486

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

In this problem, we have that:

P = 2079, I = 0.0231, t = 14

So

E = 2079*0.0231*14 = 672.3486

The amount of interest earned at the end of 14 years would be $672.3486
