The Municipality we be able to set up 597 street name boards with R2 left in the budget.

Data;

  • Amount Budgeted = R80,000
  • Cost of each board = R134

x = \frac{80000}{134}\\x = 597.01

We would have a total of 597 street names on the budget with some amount left.

We can calculated this by multiplying 597 by 134 and then subtracting the value from R80,000

597 * 134 = 79998 \\R80,000 - R79998 = R2

The Municipality we be able to set up 597 street name boards with R2 left in the budget.
