Answer:
-45
Step-by-step explanation:
-50 + 2a represents the sum of the constant -50 and twice the value of the variable a.
If a = 2.5, then -50 + 2a has the value -50 + 2(2.5) = - 50 + 5 = -45.
To find a % you want to divide the # of new members, by the total # of members.
14/34 =0.41
Since this gave you a decimal, multiplying by 100 will give you a %!
0.41 x 100 = 41%
This means that 41% of the club is new members!
Here you go there is hardly Any work to show for it
