Minchanka [31]

Answer:

The percent error in Isabel's measurement is 12.5%.

Step-by-step explanation:

Given:

Isabel thinks she has space for a 45 inch wide bookcase it turns out she only has space for a 40 inch wide bookcase.

Now, to find the percent error in Isabel's measurement.

Measurement she thinks = 45 inch.

The actual measurement = 40 inch.

So, the error in measurement = $45-40=5\ inch.$

Now, to get the percent error of the measurement:

$\frac{5}{40} \times 100$

$=\frac{500}{40}$

$=12.5\%.$

Therefore, the percent error in Isabel's measurement is 12.5%.
