THANK YOU SO MUCH!

Answer 1

1) $7 x 47 trees x 173 rows = $56, 917

2) 4 shelves: 3 3/4 x 4 = 15/4 x 4 = 15 feet required
16 feet total - 15 feet required = 1 foot left

3) $479 - $95 = $384 left to pay
$384/8 months = $48 each month

Answer 2

1.a farmer estimates it will cost $7 to maintain the trees in his orchard. If he has 47 trees in each row and there are 173 rows, find his maintainace cost for the entire orchard

$7 A farmer estimates it will cost $7 to maintain the tress in his orchard.
If it is $7/tree it would be 7 x 47 x173
If it is $7/row it is 7 x 173

2. sue has a 16 foot piece of shelving lumber. She needs to make 4 shelves. each one will be 3 3/4 long. find the length of the piece of lumber that sure has left after she hs cut all of the shelves?
4 x 3 is 12 4 x 3/4 is 3 Therefore 4x3 3/4 is 15
Subtract that from 16 and she has one foot left.

davids dad bought a washing machine that cost $479 if he paid $95 down and arranged to pay off the balance in 8 equal monthly payments what is the amount of each payment?
Start with the 479 subtract the 95 he paid down.
Take the answer to that and divide by 8.

Answer 3

1)no of trees=173 x 47=8131
cost of maintance=8131 x 7= $56,917
2) Length of lumber left=(16-4*3 3/4)
=16-4*15/4=16-15=1 ft
3) Money to be paid nin instalments=479-95=$384
so each instalment=384/8=$48 ans

Answer 4

47*173 = 8131 trees
8131 7 = $56,917

4 * 3 3/4 = 4 * 15/4 = 15
So sue will have 16-15 = 1 foot left

$479- 95 = $384 left to pay
$384/8 = $48 per month

Answer 5

1) 7$ per tree x 47trees in a row x 173 rows
total trees=47 x 173 = 8131 trees
total cost $7 x 8131 = 56917

2) one foot
3 3/4= 15/4
15/4 x 4 shelves=15 feet consumed
1 foot left

3) amnt paid = 95$
amnt left to be paid = 479 - 95 = 384
total no.of installments = 8
payment per installment = remaining amnt / no.of installments
= 384/8= 48

Answer 6

1.$45073


2. 4*3.4=13.6
16-13.6= 2.4

3. 479-95=384
384/8= 48

Answer 7

for # 1multiply all numbes remember to line up the decimals too so the anser would be 173 x 47=8031
