The right answer is Option A.
Step-by-step explanation:
Let,
x be the postcards
y be the large envelops
According to given statement;
14x+5y=12 Eqn 1
10x+15y=24.80 Eqn 2
Multiplying Eqn 1 by 3;
Subtracting Eqn 2 from Eqn 3;
Dividing both sides by 32
Putting x=0.35 in Eqn 1;
Dividing both sides by 5
Therefore, one large envelope costs $1.42
The right answer is Option A.

Answer:
Cost of 11 cans of Dog food is $9.57
Step-by-step explanation:
Cost of 5 cans of dog food = $4.35
So to find out the cost of 11 cans of dog food at the same price, we need to calculate the price of 1 can of dog food.
<u>Calculation for finding out cost of 1 can of dog food</u>
The price $4.35 which is given is the price of 5 cans
So to find the cost of 1 can, we need to divide the given price by 5
5 Cans of dog food = $4.35
1 can of dog food = 4.35 ÷ 5
1 can of dog food = $0.87
<em><u>Now to find out the price of 11 cans, we will multiply the price of 1 can with 11</u></em>
Cost of 11 cans = 11 × $0.87
= $9.57
