Question

Dylan delivers parcels.

Answer 1

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

$0.5*1.1x = 77$

$x = \frac{77}{0.5*1.1}$

$x = 140$

Dylan delivered 140 parcels on Wednesday.
