The first term of a geometric sequence is 6, and the ratio (multiplier) is 0.5. what is the sum of the first 8 terms, rounded to the nearest tenth?

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

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
