Aschool buys 200 calculators at a special price. x of them were scientific calculators at r89 a piece and the rest were financial calculators at r599 a piece. an expression, in terms of x, for the total number of financial calculators bought is

The required expression, in terms of x for the total number of financial calculators bought is given by : 200 - x

Step-by-step explanation:

Total number of calculators = 200

Price of each scientific calculator = R 89

Price of each Financial calculator = R 599

Let number of scientific calculators bought be x

So, number of financial calculators bought = 200 - x

Let total cost of buying 2000 calculators be R y

Hence, Expression for total cost of buying 200 calculators :

y = 89·x + 599·(200 - x)

And the required expression, in terms of x for the total number of financial calculators bought is given by : 200 - x
