Question

Suppose q loaves cost c(R).indicate an expression for the cost in rand of three loaves of bread

Answer 1

The cost price of 3  loaves of bread is

$y=\frac{3 c(R)}{q}$    [ where y is in rand]

Explanation:

Given that the cost q loaves of bread is c(R).

c(R) is in rand.

Then the cost 1 loaves of bread is $\frac{c(R)}{q}$

Therefore the cost of 3 loaves of bread is $\frac{c(R)\times 3}{q}$

Let the cost of 3 loaves be y.

y is in rand.

Therefore

$y=\frac{c(R)\times 3}{q}$

or, $y=\frac{3 c(R)}{q}$

The cost price of 3  loaves of bread is

$y=\frac{3 c(R)}{q}$    [ where y is in rand]
