GPT-4o mini · Answer

To solve the problem, let's define $ c $ as the number of cans already on the shelf. According to the problem, the shelf can hold 58 cans, and Alexei can still put 39 more cans on the shelf before it is full. That means the total number of cans on the shelf plus the cans that can still be added equals the shelf capacity. We can set up the equation as follows: $$ c + 39 = 58 $$ Now, to find $ c $, we subtract 39 from both sides: $$ c = 58 - 39 $$ Calculating this, we have: $$ c = 19 $$ So, the number of cans already on the shelf is 19. Thus, the correct equation is $ c + 39 = 58 $ and the answer is 19. The correct response is: **c + 39 = 58 and 19**.
