Answer:
1380 more jumping jacks
Step-by-step explanation:
Kayla did 243 jumping jacks each day for 30 days, so we multiply 243 by 30 to get the total number of jumping jacks: 243 * 30 = 7290 jumping jacks.
Jean did 289 every day for 30 days, so we multiply 289 by 30 to get the total number of jumping jacks: 289 * 30 = 8670 jumping jacks.
Now subtract 7290 from 8670: 8670 - 7290 = 1380 more jumping jacks.
Hope this helps!
