Question

He Sun bought 3 skirts for s dollars each and a jacket that costs 5 times as much as each skirt. She spent a total of $280. How much did the jacket cost?

Answer 1

The jacket cost 5 times as much as each skirt cost, which was s dollars, so it cost 5s dollars. She bought 3 skirts, so in total she spent 3s+5s dollars, or 8s dollars. If 8s=280, s=35. Each skirt cost s=35 dollars, and the jacket was 5 times that.
5*35=175
The jacket cost $175.

Answer 2

Answer:  The required cost of the jacket is $175.

Step-by-step explanation:  Given that He Sun bought 3 skirts for s dollars each and a jacket that costs 5 times as much as each skirt. She spent a total of $280.

We are to find the cost of the jacket.

According to the given information, we have

$3\times s+5\times s=280\\\\\Rightarrow 3s+5s=280\\\\\Rightarrow 8s=280\\\\\Rightarrow s=\dfrac{280}{8}\\\\\Rightarrow s=35.$

Therefore, the cost of the jacket is given by

$5\times35=175.$

Thus, the required cost of the jacket is $175.
