Question

# A builder buys 8.2 square feet of sheet metal. She used 2.1 square feet so far and

has R s 183 worth of sheet metal remaining. Write and solve an equation to find out

How much sheet metal costs per square foot ?

Hint:

### Form the equation using the given information.

○ Take variable quantities as x.

## The correct answer is: Hence, the cost of sheet metal per sq. feet is R s. 30.

### Answer:

- Step-by-step explanation:

○ Given:

Total sheet metal = 8.2 sq. feet

Used sheet metal = 2.1 sq. feet.

Worth of remaining sheet = R s. 183

○ Step 1:

Calculate remaining sheet metal.

8.2 - 2.1 sq. feet

6.1 sq. feet

So,

The remaining sheet metal is 6.1 sq. feet

○ Step 1:

Let the cost of metal sheet per sq. feet be R s. x

∴ cost of remaining sheet metal is

6.1x rupees

It is given that the cost of remaining sheet metal is 183 rupees

∴ 6.1x = 183

x =

x = 30

- Final Answer:

Hence, the cost of sheet metal per sq. feet is R s. 30.

So,

The remaining sheet metal is 6.1 sq. feet

○ Step 1:

Let the cost of metal sheet per sq. feet be R s. x

∴ cost of remaining sheet metal is

6.1x rupees

It is given that the cost of remaining sheet metal is 183 rupees

∴ 6.1x = 183

### Graph the equation

We can find the tabular values for any points of x and then plot them on the graph. But we usually choose values for which calculating y is easier. This makes plotting the graph simpler. We can also find the values by putting different values of y in the equation to get different values for x. Either way, we need points satisfying the equation to plot its graph.
