Answer:- $0.75 per kg and $0.50 per kg

let the price of sugar and rice be X and y respectively.

now ,

according to question,

3x + 2y = 3.25 $_____eq.(I)

2x + 2y = 2.50 $______eq.(II)

subtracting eq(II) from eq(I) , we get

2y will be cancelled and remains

X = 0.75 $

therefore , the price of sugar = 0.75 $ per kg.

and

substituting X = 0.75 in eq.(II) , we get

2*0.75 + 2* Y = 2.50

or, 2Y = 2.50- 1.50

or,. Y = 1/2= 0.5

hence , the price of rice is 0.5 $ per gram.

3. A savings account has a 3% interest rate. (a) Complete the ratio table shown. Show your work. Deposit ($) 100 50 300 Interest
blsea [12.9K]
We all know, savings account have "Compound Interest"

So, Here, On $100 deposit, amount of Interest = $12

So, for $50, it would be: $6

Then, for $300, it is: $36

b) If you deposit $200, then balance after 1 year, 
A = P(1 + r)^t

A = 200(1 + 0.03)^1

A = 200(1.03)
A = $206

Now, Balance with $150
A = 150 (1 + 0.03)^1
A = 150(1.03)
A = 154.5

Difference = 206 - 154.5 = $51.5

In short, Your Answer would be: $51.5

Hope this helps!
