Amanda wants to save $400 in 8 weeks. She plans to save $100 each week. Will that be enough to reach her goal?

Yes.
$100/week x 8 weeks = $800

.35 is smaller than .7 (the zero before is optional, sorry). 0.70 means theres seventy hundreths, 0.35 means theres thirty five hundreths. 100 hundreths=1
does this make sense?
hit thanks if it does. if it doesnt, I can reword it and help. no worries. I just want to be able to help.
