HELP PLSSS! IM IN A HURRY A savings account has a 3% interest rate.
(a) Complete the ratio table shown. Show your work. Deposit ($) 100 ___ 50 300
Interest ($) ___ 12 ___ ___
(b) How much more interest would you have if you deposited $200 than if you deposited $150? Show your work.

(a) Deposit ($) 100  400  50  300  

    Interest ($) 3  12  1.50  ___

(b) If you deposited 200, the interest would be $6, while if you deposited $150, the interest would be $4.50. So, you would have $1.50 more interest if you deposited $200 than if you deposited $150, or 33.33% more.

Step-by-step explanation:

(a)

100 × 0.03 = 3

0.03 × 100 is 0.03 moved 2 place values to the left, which would move the 3 to the ones place. This would make 3% of 100 equal to 3.

x × 0.03 = 12

3% of what is 12

Divide 12 by 3 to get 1% of the number, which is 4.

Now we can multiply this by 100 to get 400, which is the amount of money that was deposited.

50 × 0.03 = 1.50

3% of 100 is 3

100 ÷ 2 = 50

(3% of 100) ÷ 2 = 3% of 50

So, 3 ÷ 2 = 1.50

300 × 0.03 = 9

3% of 100 is 3

100 × 3 = 300

(3% of 100) × 3 = 3% of 300

So, 3 × 3 = 9

(b)

100 × 1.5 = 150

(3% of 100) × 1.5 = 3% of 150

So, 3 × 1.5 = 4.50

100 × 2 = 200

(3% of 100) × 2 = 3% of 200

So, 3 × 2 = 6

Now, to find how much more interest you would have if you deposited $200 than if you deposited $150, then you subtract 6 by 4.50 to get 1.50.

If you're looking for a percentage, you do 4.50 divided by 1.50 to get 3, which means that 1.50 is 1/3 of 4.50. So, the percentage of that is 33.33% with a line over the two 3's past the decimal point to indicate that the decimal repeats.

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.
