Answer (1)
Answer:【Answer】: 10【Explanation】: Let's denote the number of cookies Joy-joy started with as x. According to the problem, she baked 8 more cookies each day than the previous day. So, on the first day, she baked x cookies, on the second day she baked x+8 cookies, on the third day she baked x+16 cookies, on the fourth day she baked x+24 cookies, and on the fifth day she baked x+32 cookies. The total number of cookies she baked in five days is 150. Therefore, we can write the equation as follows: x + (x+8) + (x+16) + (x+24) + (x+32) = 150. Simplifying this equation, we get 5x + 80 = 150. Solving for x, we find that x = 14. Therefore, Joy-joy started with 14 cookies.
