Question 1.
A butterfly traveled 248 miles in three days. It flew 67 miles on Monday and 83 miles on Tuesday. How many miles did the butterfly travel on Wednesday?
Answer:
The butterfly flew 98 miles on Wednesday.
Explanation:
let m be the number of butterflies on Wednesday
(67 + 83) + m = 248
150 + m = 248
248 – 150 = 98
m = 98
