Answer:
a) 7t - 560 ≤ 140 is the required inequality to represent the situation.
Step-by-step explanation:
Let t represent the number of tickets sold.
The amount allocated by school council for all supplies = $560
The selling price of each ticket = $7
The aim to earn profit = more than $140
Goal reached if Number of tickets sold = 100
Now, SP of each ticket is $7
⇒Selling price of t tickets = t x ($7) = 7t
PROFIT = TOTAL SELLING Price - TOTAL COST
or, $140 = 7t - $560
According to the question:
7t - 560 ≤ 140
if t = 100, then the profit earned = 7(100) - 560 = 140
Hence, t = 100 is the possible solution of the given expression.
