Answer:
(D). 28
Step-by-step explanation:
We have been given that the smallest integer that can be divided by the product of a prime number and 7 while yielding a prime number.
We know that smallest prime is 2. The product of 2 and 7 is 14.
Let us divide our given numbers by 14.
(A) 7.

The quotient is not a integer or prime number.
(B). 14

We know that 1 is not a prime number.
(C) 24.

The quotient is not a integer or prime number.
(D). 28

Since 2 is a prime number, therefore, 28 is the smallest integer that can be divided by the product of a prime number and 7 and yield a prime number.
One kg of sugar = $1.40 so two kg of sugar equals $1.40 + $1.40 = $2.80
One kg of salt cost $0.55, so two kg of salt costs $0.55 + $0.55 = $1.10
To find the total price, add the cost of 2kg of sugar plus 2kg of salt together.
Total price = $2.80 + $1.10
Total price = $3.90
