Sagot :

Answer:

Dylan delivered 140 parcels on Wednesday.

Step-by-step explanation:

On Wednesday:

On Wednesday, he delivered x parcels.

Thursday:

10% more than Wednesday, so 100 + 10 = 110% of x = 1.1x

Friday:

50% pless than on Thursday, so 100 - 50 = 50% of 1.1x = 0.5*1.1*x.

THis is equals to 77. So

[tex]0.5*1.1x = 77[/tex]

[tex]x = \frac{77}{0.5*1.1}[/tex]

[tex]x = 140[/tex]

Dylan delivered 140 parcels on Wednesday.
