Final answer:
Jayla needs to sell 29 more boxes of cookies to reach her goal of 46 boxes for the school fundraiser.
Step-by-step explanation:
Jayla is participating in a school fundraiser and needs to sell a total of 46 boxes of cookies. To determine how many more boxes Jayla needs to sell, we first add up the boxes she has already sold: 4 boxes of lemon cookies, 10 boxes of chocolate cookies, and 3 boxes of oatmeal cookies. This gives us a sum of 4 + 10 + 3, which equals 17 boxes sold so far.
Next, we subtract the number of boxes sold from the total number of boxes Jayla needs to sell. This calculation is 46 - 17, resulting in 29 more boxes to be sold to reach her goal.
In conclusion, Jayla needs to sell 29 more boxes of cookies for the school fundraiser.
