Question

a) 105
b) 120
c) 135
d) 90

Answer 1

The number of two-piece swimsuits sold at Roobeezy department store is 105, which is found by subtracting the 45 one-piece swimsuits (30% of 150) from the total of 150 swimsuits.

Step-by-step explanation:

To calculate the number of two-piece swimsuits sold at Roobeezy department store, we can first determine how many one-piece suits were sold, since we know this is 30% of the total swimsuits sold. If the store sold 150 swimsuits last month, then the number of one-piece swimsuits is 30% of 150, which is:

0.30 × 150 = 45 one-piece swimsuits

Now, to find out how many two-piece swimsuits were sold, we subtract the number of one-piece suits from the total number of swimsuits:

150 (total swimsuits) - 45 (one-piece swimsuits) = 105 two-piece swimsuits

Therefore, the answer is (a) 105.
