A 600g packet of biscuits costs $2.40. Calculate How much would a 200g packet cost?

$0.8

Step-by-step explanation:

There is a relation of direct proportion between quantity of biscuit and its cost.

Let 200 g biscuit will cost $x.

Therefore,

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
