Based on the table, Josie is paid $43.75 for 5 hours work. For 1 week's work, the pay will be for 40 hours, 8 times that amount, or
.. Josie's weekly pay = 8*43.75 = 350.00
Based on the graph, Salvador gets paid $15.00 for 2 hours work. For 1 week's work, the pay will be for 40 hours, 20 times that amount, or
.. Salvador's weekly pay = 20*15.00 = 300.00
Josie earns 350 -300 = 50 more each week than Salvador. For Josie to earn 1000 more, we can solve the equation
.. 50*weeks = 1000
.. weeks = 1000/50 = 20
It will take Josie 20 weeks to earn $1000 more than Salvador does in the same period.
