Plz help me i really need it

Cheryl deposits $7500 into the bank. She cannot withdraw or deposit any more money for 6 years. She earns 6% interest during that time.

How much interest will she have earned at the end of 6 years? (just put the numerical value, no $ sign) it is 2700

What will her new balance be when she is finally able to withdraw her money? (just put the numerical value, no $ sign)

plz show work

Assuming the bank is using simple interest, and not compound interest, then

i = P*r*t

i = 7500*0.06*6

i = 2700

is the amount of money Cheryl earns in simple interest. This adds onto the original amount deposited (7500) to get 7500+2700 = 10200

b is the final answer! : )

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
