Arnold buys 3 3/5pounds of green grapes for $1.85 per pound. He buys 3 3/5
pounds of red grapes for $2.30 per pound. Which expression can be used to determine the total cost, in dollars, of the grapes Arnold buys?

Answers

The expression can be used to determine the total cost, in dollars, of the grapes Arnold buys is given as:

Total cost = cost of green grapes bought + cost of red grapes bought

The total cost in dollars is $ 14.94

Solution:

Given that Arnold buys 3 (3)/(5) pounds of green grapes for $1.85 per pound.

Also given that He buys 3(3)/(5) pounds of red grapes for $2.30 per pound.

To find:  total cost in dollars of the grapes Arnold buys

Cost of green grapes bought:

Arnold buys 3 (3)/(5) pounds of green grapes for $1.85 per pound.

Cost per pound = $ 1.85

So cost of 3 (3)/(5) pounds of green grapes for $1.85 per pound is given as:

\rightarrow 3 (3)/(5) * 1.85\n\n\rightarrow (18)/(5) * 1.85\n\n\rightarrow 3.6 * 1.85 = 6.66

Thus total cost for buying green grapes = $ 6.66

Cost of red grapes bought:

Arnold buys 3(3)/(5) pounds of red grapes for $2.30 per pound.

Cost per pound = $ 2.30

So cost of 3(3)/(5) pounds of red grapes for $2.30 per pound is given as:

\rightarrow 3(3)/(5) * 2.30\n\n\rightarrow (18)/(5) * 2.30\n\n\rightarrow 3.6 * 2.30 = 8.28

Thus total cost for buying red grapes = $ 8.28

The expression can be used to determine the total cost, in dollars, of the grapes Arnold buys is given as:

Total cost = cost of green grapes bought + cost of red grapes bought

Total cost = $ 6.66 + $ 8.28 = $ 14.94

Thus total cost in dollars is $ 14.94

there are 32 peanuts in a bag. Elliott takes 25 percent of the peanuts from the bag. then zaire takes 50 percent of the remaining peanuts. how many peanuts are left in the bag?

Answers

1) we calculate the number of peanuts in the bag after Elliott take 25% of the peanuts form th bag.

number of peanuts in the bag after elliot take 25%=32-(25/100)32=32-8=24.

2) we calculate the number of peanuts in the bag after Zaire takes 50% of the remaining peanuts.

number of peanuts in the bag after Zaire takes 50%=24-(50/100)24=24-12=
=12

50+25%=75%

32*75%=24

32-24=8

Thus, there are 8 peanuts remaining.
