we know that

total shoppers=150

Part A

shoppers with computer access at home=47+16=63

we have that

150 represents 100%

so

Applying proportion

Find out how much percentage represents 63

100/150=x/63

solve for x

x=(100/150)*63

x=42%

The answer Part A is 42%

Part B

we have that

shoppers than not have an email account=16+74=90

150 represents 100%

Applying proportion

Find out how much percentage represents 90

100/150=x/90

solve for x

x=(100/150)*90

x=60%

the answer part B is 60%
