Question

Emma is trying to buy a video game console that costs $249. she already saved $60 and plans to save $22 per week. after how many weeks will she have saved enough money for the video game console?

Answer 1

since she already have 60, just 249 - 60, which means she still have 189 to go.
now divide 189 by 22,
and you get 8.59...
and since it's not a whole number, and you cannot say 8.59... week, to round up, we just say she needs 9 week to save enough money
