You could estimate by doing 600x3=1800
(becasuse of the 0's in 600 it is easier to do 6*3=18 and then add two 0's to the end 1800)
then you simply multiple 640x3=1920
Step-by-step explanation:
4 9/10 + 3 7/10
49/10 + 37/10(turned into an improper fraction
86/10 ( both figures added )
=8 6/10(result)

It is a solve for x equation. It is written as 300=x (20-14) first you do the subtraction in the brackets 300=x (6) then divide both sides by 6 to find x 50=x it would take 50 weeks for him to save 300$ (feel free to check that by putting 50 in for x and solving)
