To determine the total number of T-shirts sold by the band, we can use the information that 150 shirts were sold, which constitutes 30% of the total sales.
Let \( x \) be the total number of shirts sold.
According to the information: \[ 0.30x = 150 \]
To find \( x \), we can solve for it by dividing both sides by 0.30: \[ x = \frac{150}{0.30} = 500 \]
This means the total number of T-shirts sold by the band is 500.
Now let's evaluate the statements:
- The band sold 180 shirts. - False (they sold 500 shirts).
- The total sales will be less than 150 shirts. - False (the total is 500 shirts).
- The band sold 500 shirts. - True (as calculated).
- The total sales will be greater than 150 shirts. - True (the total is 500 shirts).
So, the two true statements are:
- The band sold 500 shirts.
- The total sales will be greater than 150 shirts.
