Answer:

a =5

Step-by-step explanation:

4a -3 = 2a +7

Subtract 2a from each side

4a-2a -3 = 2a-2a +7

2a-3 =7

Add 3 to each side

2a-3+3 = 7+3

2a=10

Divide each side by 2

2a/2 = 10/2

a =5

Mars2501 [29]

Answer:

There can be at most 12 attendees in a corporate team-building event.

Step-by-step explanation:

Let x denotes number of attendees in a corporate team-building event.

Fixed cost = $19

Cost charged per attendee = $1

Budget for the corporate team-building event = $31

Therefore,

19+1(x)\leq 31\\19+x\leq 31\\x\leq 31-19\\x\leq 12

So, there can be at most 12 attendees in a corporate team-building event.
