Answer:
[tex]P=\$362.5[/tex]
Step-by-step explanation:
From the question we are told that
Preston Earns \triangle x=$64-$81
Number of days D=5 days
Generally the average amount of money made by Preston is given by
[tex]X_a_v_g=\frac{64+81}{2}[/tex]
[tex]X_a_v_g=\$72.5[/tex]
Generally a reasonable estimation of how much Preston will earn if he works 5 days P is mathematically given by
[tex]P=72.5*5[/tex]
[tex]P=\$362.5[/tex]
