Final answer:
Jimmy will take 7 more days to finish tiling the house.
Step-by-step explanation:
To find out how many more days Jimmy will take to finish tiling the house, we first need to determine the remaining area that needs to be tiled. Jimmy has already tiled 30% of the house, which is equal to 30% * 1850 = 555 square feet. So, the remaining area is 1850 - 555 = 1295 square feet.
Each day, Jimmy tiles 185 square feet. To find out how many more days he will take, we need to divide the remaining area by the area he tiles each day: 1295 / 185 = 7.
Therefore, it will take Jimmy 7 more days to finish tiling the house.
