They are each paid according to the number of leaflets they delivered.

How much did each person earn?

Zack earned £125, Jack earned £75, and Sasha earned £50

Step-by-step explanation:

Considering the number of leaflets delivered

Zack 50%, Jack 30% and Sasha 20%

Total delivered = 50 + 30 + 20 = 100%

If they earn £250 on the 100% delivery, then each will have as shown below

Zack = (50/100)*250

= 5*25

= £125

Jack = (30/100)*250

= 3*25

= £75

Sasha = (20/100)*250

=2*25

= £50

£125, £75 and £50

Step-by-step explanation:

Zack delivered 50%

Therefore, Zack earned

50% of £250

50/100 x £250

0.5 x 250

£125

Zack earned £125

Jack delivered 30%, therefore

Jack earned

30% of £250

0.3 x £250

£75

Jack earned £75

Sasha delivered 20%

Therefore, Sasha earned 20% of £250

20/100 x £250

0.2 x £250

£50

Sasha earned £50

Zack + jack + Sasha = £250

£125 + £75 + £50 = £250

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
