Question

Given the function, q = 2.5p, find the values of x and y from the table.

• A. x = 2.5, y = 5
• B. x = 5, y = 6
• C. x =6, y =10
• D. x = 6, y = 5

Answer 1

The correct option is B x = 5, y = 6

The function here follows the rule q = 2.5p

When p = 2,
<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> ⇒ q = 2 $\times$ 2.5 = 5 which becomes equal to x.
∴ x = 5

When q = 15,
p = 15 ÷ 2.5 ⇒ 6 which becomes equal to y.
∴ y = 6
