Answer:
the T-shirt cost is $16
Step-by-step explanation:
first, we know the total cost of the shirt and book was $28 so we substract 12 from 28 wich gives us 16 so the cost of the shirt is $16.
37.99 * 25%= 9.497 or $9.50 tip
x is equal to 1754, so it's 1754
We can use FOIL to solve.
(x + 7)(x + 10)
(x * x) + (x * 7) + (7 * x) + (7 * 10)
x² + 7x + 7x + 70
x² + 14x + 70
Best of Luck!
