Answer:
$500
Step-by-step explanation:
substitute the values for X & S in the equation from part A:
y=20x + 0.15s
x=($20x25) + (0.15x$0)
= $500
10.50 x 0.2 = $2.10
Therefore, 20% of $10.50 is $2.10
With 20% off, the book will cost
10.50-2.10 = $8.40
half an hour past 7, will be 7 plus 30 minutes then 7:30.
we could also come from the other way, and say is 30 minutes before 8 o'clock.
