on monday, ivy crawled one inch more than tuesday. on tuesday, ivy crawled twice as much as on wednesday. on wednesday, ivy crawled 4 inches. how many inches did ivy crawl each day

To solve this problem, we need to find out how many inches Ivy crawled on Monday, Tuesday, and Wednesday.

Let's start with what we are given:
On Wednesday, Ivy crawled 4 inches.
On Tuesday, Ivy crawled twice as much as on Wednesday, so she crawled 4 x 2 = 8 inches.
Finally, on Monday, Ivy crawled one inch more than on Tuesday, meaning she crawled 8 + 1 = 9 inches.

Therefore, Ivy crawled:
- On Monday: 9 inches
- On Tuesday: 8 inches
- On Wednesday: 4 inches
