Basile [38]

Answer:

His average this season is 154 yards a game.

Step-by-step explanation:

This question can be solved by a simple rule of three.

Last season's numbers(110 yards a game) is 100% = 1 decimal

This season number(x yards a game) is an increase of 40% over last season, so 40% + 100% = 140% = 1.40 decimal.

So

110 yards a game - 1

x yards a game - 1.40

x = 110*1.40 = 154

His average this season is 154 yards a game.
