Final answer:
The difference in inches of rain that fell this week compared to last week is 3.5 inches.
Step-by-step explanation:
To find the difference in inches of rain that fell this week compared to last week, we need to calculate the total inches of rain for each week. This can be done by multiplying the number of days by the amount of rain that fell each day.
For this week, 2 inches of rain fell each day for 4 days, so the total inches of rain is 2 x 4 = 8 inches.
Last week, 1.5 inches of rain fell each day for 3 days, so the total inches of rain is 1.5 x 3 = 4.5 inches.
To find the difference, we subtract the total inches of rain for last week from the total inches of rain for this week: 8 - 4.5 = 3.5 inches.
