Answer:
$70
Step-by-step explanation:
you can see there is a 7 in the ones place meaning it should round up not down. rounding up from 67 to the tens place gives you 70
Your friend's estimate is wrong because you pay $2.40 for 3/4 pound of grapes, which means 1/4 pound of grapes equals $0.80, you friend wants to any for one pound, so your friend must use 1/4 times 4 equals $0.80 times 4=$3.20 for a pound of grapes
5/8 = 0.625
Hope this helps!
