Nick works on a tree farm, bundling
seedlings. His workweek is 40 h, and he can
complete three bundles per hour. He needs
to choose one of the following rates of pay:
i) $8.75 per hour
ii) $4.75 per hour plus $1.35 per bundle
iii) $2.75 per bundle
a) Write an algebraic expression that
shows Nick’s weekly earnings at each
rate of pay.
b) Which rate of pay should Nick choose?
Use your algebraic expressions to
support your answer.
Solution:
a)
i) Algebraic equation for the first rate ($8.75 per hour):
y = 8.75t, where t is time
ii) Algebraic equation for the second rate ( $4.75 per hour plus $1.35 per bundle ):
y = 4.75t + 3 * 1.35t
y = 4.75t + 4.05t
y = 8.80t, where t is time
iii) Algebraic equation for the third rate ($2.75 per bundle):
y = 3 * 2.75t
y = 8.25t
b)
When t (time) = 40 hours
i) y = 8.75 * 40
y = 350
So when Nick works 40 hours/week, his salary with the first type of rate will be $350
ii) y = 8.80 * 40
y = 352
So when Nick works 40 hours/week, his salary with the second type of rate will be $352
iii) y = 8.25 * 40
y = 330
So when Nick works 40 hours/week, his salary with the third type of rate will be $330
As we can see the most profitable rate is the 2nd rate ($4.75 per hour plus $1.35 per bundle), where he can earn $352.
