Question

Write a mathematical sentence that expresses the information given below.

Use c as your variable name. If necessary:
type <= to mean
or >= to mean 2.
Henry had charged 612 dollars to his credit card. The cost of his next
purchase caused him to exceed his credit limit of 2000 dollars.

Answer 1

612 +c > 2000

Explanation:

You want a mathematical expression for the scenario that a charge of 'c' to Henry's credit card, after a charge of $612, causes his credit limit of $2000 to be exceeded.

Balance

If Henry had charged $612 and charges 'c' more, the total of charges is 612+c. If that exceeds his $2000 limit, we can say ...

612 + c > 2000

__

Additional comment

We don't use the symbol ≥ because the limit is exceeded, not just reached.
