On a deposit of $50 at a simple interest rate of 9%, how much interest will you earn after 12 vears?

Interest after 12years is $54

Step-by-step explanation:

Simple interest (I) is calculated by Principal x Rate x Time

From the question given, Principal= $50; Rate = 9% = 9/100 = 0.09

Time= 12years

Slot the values into the formula

I =$50 x 0.09 x 12

I =$54

I hope this is clear, do have a great day!

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
