Question

The expresion 14.42d + 12.24c can be used to find the total cost of d punds of almonds and c pounds of cashews how much does it cost to buy 3 and a half pounds of almounds and 3 and a half punds of cashews

Answer 1

Answer:

Therefore the total cost of $3\frac{1}{2}$ pound of almonds and $3\frac{1}{2}$ pound of cashews is

$y=\frac{36.05}{d}+\frac{30.6}{c}$

[Where y is in $]

Step-by-step explanation:

[The unit of price is not given, I assume the unit of cost as $]

Given expression is 14.42 d + 12.24 c .

Where the amount of almond is denoted by d pounds.

and  the amount of cashews is denoted by c pounds.

The cost price of d pound of almond is $14.42.

The cost price of 1 pound of almond is $\ \frac{14.42}{d}$

Then the cost of $3\frac{1}{2}$ pound of almond is $=\ \frac{ 14.42 \times3 \frac{1}{2} }{d}$

                                                                 $=\ \frac{36.05}{d}$

Again from the given expression we get that,

The cost price of c pound of cashews is $12.24

The cost price of 1 pound of cashews is $=\ \frac{12.24}{c}$

Then the cost of $3\frac{1}{2}$ pound of cashews is $=\ \frac{ 12.24 \times3 \frac{1}{2} }{c}$

                                                                    $=\ \frac{30.6}{c}$

Therefore the total cost of $3\frac{1}{2}$ pound of almonds and $3\frac{1}{2}$ pound of cashews is

y = $=\frac{36.05}{d}+\frac{30.6}{c}$

[Where y is in$]
