You are selling tickets to a play. You have sold (3t+2) tickets for $5 each and (2t+5) tickets for $7 each. Write an expression

aliya0001 [1]

Given that the number of tickets that are sold for $5 is (3t+2) tickets.

The number of tickets that are sold for $7 is (2t+5) tickets.

We need to determine the expression that represents the total number of tickets sold and the simplified expression.

<u>Total number of tickets sold:</u>

The expression for (3t+2) tickets sold for $5 is given by

$5(3t+2)$

The expression for (2t+5) tickets sold for $7 is given by

$7(2t+5)$

The expression for the total number of tickets sold is given by

$5(3t+2)+7(2t+5)$

Thus, the expression that represents the total number of tickets sold is $5(3t+2)+7(2t+5)$

<u>Simplified expression:</u>

We need to simplify the expression $5(3t+2)+7(2t+5)$

Hence, let us multiply the terms within the bracket.

Thus, we get;

$15t+10+14t+35$

Adding the like terms, we have,

$29t+45$

Thus, the simplified expression is $29t+45$
