To calculate the charge for a load of bricks, including delivery, they use this equation

c = 0.42b + 25 where c is the charge per load and b is the number of bricks. What is the delivery charge per load. They don't give you the number of bricks so ?

So — you cannot solve unless you have the value for b or c or another equation with both b and c.

Sorry that I cannot be of more help. Thanks for asking.

To calculate the delivery charge per load, we need to use the given equation: c = 0.42b + 25, where c is the charge per load and b is the number of bricks.

However, since they did not provide the number of bricks, we cannot determine the exact delivery charge per load without that information. The equation mentioned above is used to calculate the charge based on the number of bricks.

If you have the number of bricks, simply substitute that value into the equation to find the corresponding charge per load, which would be the delivery charge.
