Question

The variables x and y are related proportionally. When x = 8, y = 14. Find y when x = 32.

Answer 1

y = 56

Explanation:

given that x and y are proportional then

y = kx ← k is the constant of proportionality

to find k use the given condition y = 14 when x = 8

k =
`(y)/(x)` =
`(14)/(8)` =
`(7)/(4)`, thus

y =
`(7x)/(4)`

when x = 32

y =
`(7(32))/(4)` = 56
