ivanzaharov [21]

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

<h3>Number of Street Boards in the Budget</h3>

The number of streets boards that can be produced in the budget is calculated by dividing the total amount budgeted by the cost of each street board. This is done mathematically as

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.
