The given data is
t, h: 0 2 4 6 8 10
r(t), L/h: 8.6 7.9 6.8 6.4 5.7 5.3
The lower and upper estimates for the total amount that leaked may be computed as the Left and Right Riemann sums.
The shape of the graph of r versus will determine which of the two sums yields an upper or lower sum.
The plot of the graph is shown below.
The Left Riemann sum is
Sl = 2*(8.6+7.9+6.8+6.4+5.7) = 70.8 L
The Right Riemann sum is
Sr = 2*(7.9+6.8+6.4+5.7+5.3) = 64.2 L
Answer:
The lower estimate for oil leakage is 64.2 L
The upper estimate for oil leakage is 70.8 L

Which statement is true:
a) Jill will make less money if they each work 4 hours.
b) Jill's hourly rate is $3 more than kara's.
c) Kara charges $14 and hour for babysitting two children.
d) Kara's fee for the second child is $5.
Answer:
(D)Kara's fee for the second child is $5.
Step-by-step explanation:
From the table above,
Jill Charges an hourly rate of $11
Kara charges an hourly rate of $9 and an additional $5 charge for more than one child. Therefore, the statement that is true is Option D.
Kara's fee for the second child is $5.
All other options are incorrect.
<u>Check</u>
Option A: In four hours, Jill will make $44 while Kara will make $41
Option B: Jill's hourly rate is $2 more than Kara's, NOT $3.
Option C: Kara charges $9 an hour, NOT $14.
