Question

Which is a reasonable estimate of hourly pay for Joanna and Richard?

Answer 1

The answer is B, Joanna earns $11 and Richard earns $8.50

Answer 2

Answer:

Option B is correct.

Step-by-step explanation:

If we take the day 4 earnings, the graph shows their 32 hours earnings. $4\times8=32$

We can see that Joanna earns $350 at day 4. So, her hourly wage is :

$\frac{350}{32}= 10.93$ ≈ $11.00 (approx)

And Richard earns approximately $270 for 32 hours. So, his hourly wage is:

$\frac{270}{32}=8.43$ ≈ $8.50 (approx)

We can also check the average by taking day 3 wages.

Joanna earns approximately $260 in 24 hours. So, her hourly wage is :

$\frac{260}{24}= 10.83$ ≈ $11.00

Richard earns $200 approx in 24 hours. So, his hourly wage is :

$\frac{200}{24}= 8.33$ ≈ $8.50 or 8.00 (this is not option)

Hence, after calculating the approximate wages, we can see that Joanna earns approx $11.00 per hour and Richard earns approx $8.50

Therefore, option B. Joanna earns $11.00 an hour; Richard earns $8.50 an hour - is true.
