Explanation:

Step1: Calculate midpoint for 7-13

$\frac{7+13}{2} = 10$

Step2: Calculate midpoint for 14-20

$\frac{14+20}{2} = 17$

Step3: Calculate midpoint for 21-27

$\frac{21+27}{2} = 24$

Step4: Calculate midpoint for 28-34

$\frac{28+34}{2} = 31$

Step5: Calculate midpoint for 35-41

$\frac{35+41}{2} = 38$

Answer:

Amount	Midpoints
14-20	17
21-27	24
28-34	31
35-41	38
