Final answer:
To determine the number of different ISU computer science shirts being sold, we use the counting principle to multiply the options for each characteristic: 7 colors, 5 sizes, 2 patterns, and 2 sleeve lengths, resulting in 140 different shirts.
Step-by-step explanation:
The question asks us to calculate the number of different ISU computer science shirts being sold, given certain variations in color, size, pattern, and sleeve length. To find the total number of combinations, we can use the counting principle, which states that if one event can occur in 'm' ways and a second independent event can occur in 'n' ways, then the two events can occur in 'm x n' ways.To find the number of different shirts being sold, we need to multiply the number of choices for each attribute. There are 7 colors, 5 sizes, 2 options for striped or solid, and 2 options for long sleeve or short sleeve. So the total number of different shirts is:
Total = 7 colors * 5 sizes * 2 (striped or solid) * 2 (long sleeve or short sleeve)
Total = 7 * 5 * 2 * 2Total = 140
The company is selling 140 different shirts in total.
Here, we have:
- 7 colors
- 5 sizes
- 2 patterns (striped or solid)
- 2 sleeve lengths (long sleeve or short sleeve)
To find the total number of different shirts, we multiply the number of options for each characteristic:
Total number of shirts = 7 (colors) x 5 (sizes) x 2 (patterns) x 2 (sleeve lengths) = 140 different shirts.
Therefore, the store is selling 140 different ISU computer science shirts.
