Answer:
$66.50
Explanation:
lets break this down a bit:
the tickets are $16 each
there is an additional $2.50 added when tickets are bought online, its a one time fee and does not apply to every ticket
n represents the amount of tickets bought
you're on the right track so far, the expression is as follows:
16n +2.50 <---n is placed next to the 16 because we are calculating the amount of tickets bought and their price plus the one time service fee of $2.50
we are then told that 4 tickets were bought
in this expression, n = 4, so we substitute 4 into the equation for n
16(4) + 2.50
16 x 4 = 64
instead of multiplying like you did on the worksheet, you would add since the original expression we wrote plus 2.50, not times 2.50
64 + 2.50 = 66.50
so, the total price for 4 tickets bought online is $66.50
you were on the right track! let me know if you need anything else cleared up about expressions
