<h3>The total money earned by Rita on Monday = $158</h3>
Step-by-step explanation:
The rate by which Rita is paid first 8 hours = $16
The next per hour rate after 8 hours = times the usual rate.
Now, 1.5 times $16 = 1.5 x 1 6 = $24
So, for each hour worked after 8th hour, Rita is paid $24 per hour.
Now, the intervals she has worked are:
(a) from 8:15 to 12: 45 pm
So, the number of hours worked = 45 minutes + 45 minutes + 3 hours
= 4 hours 30 minutes .... (1) (as 60 minutes = 1 hour)
(b) break of 45 minutes after 12: 45 = 12: 45 + 45 minutes
= 12 hour 90 minutes = 1 : 30 P M
So, she started working at 1: 30 and worked till 6: 15
So, the number of hours worked = 30 minutes + 15 minutes +4 hours
= 4 hours 45 minutes .... (2)
So, by adding (1) and (2) the total hours worked by Rita
= 4 hours 30 minutes + 4 hours 45 minutes
= 8 hours 75 minutes = 9 hours 15 minutes
9 hours 15 minutes = ( 8 + 1 .25 ) ( 15 minutes = 0.25 of an hour)
So, the payment is ( 8 x (16) + 1.25 (24) )
= 128 + 30 = 158
Hence, the total money earned by Rita = $158
The answers to the question are are the equations
y = 0.08x²-1.6x+13
y = 0.08(x-10)²+5
<h3>How to solve for the system of equations</h3>David starts at (20, 13) and skates along a path that can be modeled by a quadratic function with a vertex at (10, 5).
Vertex form of quadratic function is
y =
13 = a(x-10)²+5
let x = 20
a(20-10)²+5
13 = 100a + 5
take like terms
13 - 5 = 100a
8 = 100a
divide through by 100
a = 0.08
hence the equation would be
y = 0.08(x-10)²+5
