Answer 2

Calculation of the Price Discrepancy

To find out how many times more expensive 7 shirts are compared to the jacket, we can use the given information that the price of 4 shirts constitutes 87% of the jacket's cost.

Let's calculate the cost of 1 shirt as a percentage of the jacket's cost: - 87% of the jacket's cost is equivalent to the cost of 4 shirts. - Therefore, the cost of 1 shirt is 87% divided by 4, which equals 21.75% of the jacket's cost.

Now, we can calculate the cost of 7 shirts and compare it to the cost of the jacket.

Cost Comparison

The cost of 7 shirts can be calculated as follows: - 7 shirts cost 7 times the cost of 1 shirt. - Therefore, the cost of 7 shirts is 7 multiplied by 21.75%, which equals 152.25% of the jacket's cost.

Conclusion

So, 7 shirts are approximately 1.52 times more expensive than the jacket.

This calculation is based on the given information and the percentage relationship between the cost of the shirts and the jacket
