Answer:
the expression would be y=75x+100
Explanation:
so what u would do is have multiples of 75. the worker gets paid 75 per hour, so in the chart u do 75, 150, so on. the flat fee is 100 dollars, this the y intercept in the equation. the 75x is the slope. so for the question, it asks how much it costs for 5 hours. here u would do 5 times 75. hope this helps :)
