First, what you would do is multiply 140 and 20%. Which would give you: 28

Then you would multiply 28 by 4 and get 112


Hope this helps!!(:

apologiabiology
percent means parts out of 100
20%=20/100=2/10=1/5

20% of what she earned earned per week
'of' means multiply
20% of what she earned per week means
1/5 times what she earned per week

140 per week earned
1/5 of per week=saved
1/5 of 140=1/5 times 140=140/5=28

she saved this for 4 weeks
at least 28 saved per week for 4 weeks=28 times 4=102
she saved at least102 total
saved>$102
