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 [tex]3 \frac{3}{5}[/tex] pounds of green grapes for $1.85 per pound.
Also given that He buys [tex]3\frac{3}{5}[/tex] 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 [tex]3 \frac{3}{5}[/tex] pounds of green grapes for $1.85 per pound.
Cost per pound = $ 1.85
So cost of [tex]3 \frac{3}{5}[/tex] pounds of green grapes for $1.85 per pound is given as:
[tex]\rightarrow 3 \frac{3}{5} \times 1.85\\\\\rightarrow \frac{18}{5} \times 1.85\\\\\rightarrow 3.6 \times 1.85 = 6.66[/tex]
Thus total cost for buying green grapes = $ 6.66
Cost of red grapes bought:
Arnold buys [tex]3\frac{3}{5}[/tex] pounds of red grapes for $2.30 per pound.
Cost per pound = $ 2.30
So cost of [tex]3\frac{3}{5}[/tex] pounds of red grapes for $2.30 per pound is given as:
[tex]\rightarrow 3\frac{3}{5} \times 2.30\\\\\rightarrow \frac{18}{5} \times 2.30\\\\\rightarrow 3.6 \times 2.30 = 8.28[/tex]
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
