A club is producing posters. If the cost of producing one poster
is 10 Egyptian pounds and the shipping cost of an order of any size is 27 Egyptian
pounds, what is the total cost of producing and shipping an order of 𝑥 posters?
So what we’re gonna do with this
question is form an algebraic expression. And we’ve got some information here
to help us. So we know that the cost of
producing one poster is 10 Egyptian pounds. The shipping cost of any size is 27
Egyptian pounds. And what we’re trying to find the
total cost of producing and shipping is an order of 𝑥 posters.
Well, our production cost is gonna
be equal to 10, because it’s 10 Egyptian pounds per poster, multiplied by the number
of posters. Well, we’ve already said that is
𝑥. And using our algebraic notation,
we’re gonna write this as 10𝑥. And our shipping cost is 27
Egyptian pounds because this doesn’t change with the number of posters that there
are. And it’s worth noting that these
are both Egyptian pounds, so 10𝑥 Egyptian pounds and 27 Egyptian pounds.
So therefore, if we want to produce
an expression for the whole lot, it’s gonna be 10𝑥 plus 27 Egyptian pounds. So this is the total cost of
producing and shipping an order of 𝑥 posters.
