Final answer:
If tuna salad sandwiches represent 25% of a sandwich shop's sales, then out of 200 total sandwiches sold in a week, 50 of them would be tuna salad sandwiches.
Step-by-step explanation:
To calculate the number of tuna salad sandwiches sold by the sandwich shop, we'll need the percentage that tuna salad sandwiches represent of the total sales. Since this percentage is not provided in the question, let's assume for this example that tuna salad sandwiches make up 25% of the shop's sales. If the shop sells 200 sandwiches in a week, and tuna salad represents 25% of the sales, you would calculate the number sold by multiplying the total number of sandwiches by the percentage:
Total number of tuna salad sandwiches = Total sandwiches sold × Percentage of tuna salad sandwiches
Total number of tuna salad sandwiches = 200 × 0.25
Total number of tuna salad sandwiches = 50
Therefore, the sandwich shop sells 50 tuna salad sandwiches in a week if they sell 200 sandwiches in total and tuna salad sandwiches represent 25% of their sales.
