To determine the total number of T-shirts sold by the band, we can use the information given: 120 shirts were sold, which represents 30% of the total sales on Sunday.
Let the total sales be represented as \( x \).
According to the problem:
\[ 0.30x = 120 \]
To find \( x \), divide both sides by 0.30:
\[ x = \frac{120}{0.30} = 400 \]
So, the total number of T-shirts sold by the band is 400.
Now, let's evaluate the statements:
- The band sold 400 shirts. (True)
- The total sales will be less than 120 shirts. (False; the total is 400)
- The band sold 150 shirts. (False; the total is 400)
- The total sales will be greater than 120 shirts. (True; the total is 400)
The two true statements are:
- The band sold 400 shirts.
- The total sales will be greater than 120 shirts.
