Final answer:
The equation in standard form that models the possible combinations of t-shirts and shorts is: 4.50x + 6y = 108.
None of the given options is correct
Step-by-step explanation:
To write an equation in standard form that models the possible combinations of t-shirts and shorts, we need to consider the cost of each item and the total amount of money available. Let's break it down:
T-shirts cost $4.50 each and shorts cost $6 each. If you have enough money to buy 12 t-shirts and 9 pairs of shorts, you need to find the total cost of these items.
The total cost of 12 t-shirts would be 12 * $4.50 = $54. The total cost of 9 pairs of shorts would be 9 * $6 = $54.
Therefore, the total amount of money available is $54 + $54 = $108.
The equation in standard form that models the possible combinations of t-shirts and shorts is:
4.50x + 6y = 108
