Every X to Y is being multiplied by -4. I hope this helps! Please check out my page for my question. Thanks!
Answer:
E = 12.20(h) - 7.15
h = 6.82 hours
Given:
Pay hour = $12.20 per hour
Bus fare = $7.15
1.Equation:
Assume
She has work for "h" hours
Total earning = E
So,
E = 12.20(h) - 7.15
If,
Total earning = E = $90.45
So,
E = 12.20(h) - 7.15
90.45 = 12.20(h) - 7.15
h = 6.82 hours
10% = 50
30% = 150
1% = 0.5
2% = 1
150 + 1 = 151 books should be mysteries
