C. Directly; $3. 23

D. Directly; $5. 46

Answer 1

In linear equation, $5.46 is  the cost of apple .

What is linear equation explain with example?

• An equation with only one variable is referred to as a linear equation in one variable.
• It has the mathematical formula Ax + B = 0, where A and B can be any two real numbers, and x is an unknowable variable with just one possible value. One such linear equation in one variable is 9x + 78 = 18.

We have to find cost of 4.2 pounds of apple

hence,

cost of 4.2 pounds of apple = cost of one pound of Apples * 4.2

                                              = $1.30 * 4.2 = $5.46
