7 minutes is the answer but check with the teacher first
Answer:
equation: c = 4.80h + 18.30, cost for four hours: (4, 37.5)
Step-by-step explanation:
the equation is c = 4.80h + 18.30 because 18.30, the initial cost, is the y-intercept and because each hour costs $4.80. the cost for four hours would be (4, 37.5) because it costs $37.5 to skate for four hours.
To find the probability, we do 78% to the third power, which is 0.474552 or when rounded 0.475
C. 7.5
3/4 = .75
7.5/10 = .75
