Answer:
algebraic expression is Y = 2x + 20
where x is the earning for last year
Y is the earning for this year
Explanation:
Let the earning of club in last year be x
given
The club earned$20 more than twice what it earned last year
twice the earning of last year = 2x
$20 more than twice the earning of last year = 2x +20
Earning this year = 2x +20
where x is the earning for last year
let the earning for this year be y
Y = 2x +20
Thus, algebraic expression is Y = 2x + 20
