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.
8.2 - 2.1 sq. feet6.1 sq. feetSo,
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 rupeesIt is given that the cost of remaining sheet metal is 183 rupees
∴ 6.1x = 183
x = x = 30Related Questions to study

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.
