Answer:
2013 bestie
Step-by-step explanation:
The expression will look like this. (3*6)+4
Average: about 87%
Her english grade affects her average because it is the lowest out of all of the grades which brought her average grade down.
not sure about this: To bring her average higher, she should probably try more in english or study. (not sure about this one)
Step by Step:
Add up all of her scores:
86 + 72 + 93 + 87 + 93 + 100 + 80
it equals 611
Since we added up 7 scores, we divide 611 by 7
611 divided by 7 is 87.285...
So her average is about 87%
Divide 4.55 by 0.13 (the cost of each bolt) to find out how many bolts Heidi can buy!
$4.55 ÷ $0.13 = 35
Heidi can buy 35 bolts with $4.55 !1
