Answer:
b = a² + 2a
Step-by-step explanation:
a + 1 = √(b + 1)
(a + 1)² = b + 1 (Square both sides)
a² + 2a + 1 = b + 1 (Expand left side)
a² + 2a = b (Subtract 1)
A = 1/4 = 0.25 = 25%
b = 1/16 = 0.0625 = 6.25%
c = 1/8 = 0.125 = 12.5%
d = 1/4 = 0.25 = 25%

Answer:
$8.50 per hour
Step-by-step explanation:
Alyssa worked 3 hours on Sunday and 4.2 hours on Monday
Total Number of hours Alyssa worked= Number of hours she worked on Sunday+Number of hours she worked on Monday=(3+4.2)=7.2 Hours
Total amount she earned if she is paid in a hourly rate=(Total Number of hours she worked×Money she earns per hour)
Replacing;
Total amount she earned=$61.20, Number of hours she worked=7.2, Money she earns per hour is unknown=M
61.20=7.2×M
Solving for M
(7.2×M)/7.2=61.20/7.2
M=$8.50 per hour
The money she earns per hour=$8.50
