Let the number of financial calculators purchased = "y"

So, x + y = 200

200 - x = total number of financial calculators purchased

Hope I helped!! xx

Answer:

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
