Final answer:
The value of t, the number of toys in the bigger box, is 16 as found by subtracting the number of toys in the smaller box from the total number of toys.
Step-by-step explanation:
To find the value of t, the number of toys in the bigger box, we can set up an equation using the given information that Ashley bought a total of 28 toys and that the smaller box contains 12 toys. The equation would be:
t + 12 = 28
To solve for t, we need to subtract the number of toys in the smaller box (12) from the total number of toys (28):
t = 28 - 12
t = 16
Therefore, the bigger box contains 16 toys.
