Three sweaters, striped one is cheaper than cartoon one, 25 yuan, hooded one is more expensive than cartoon one 18 yuan, hooded one is more expensive than striped one.

Stone help answer:

Step 1. The sentence "hooded model is more expensive than cartoon model 18 yuan" can be expressed by the formula: hooded model = cartoon model+18 yuan.

Two consecutive steps. "Stripes are cheaper than comics, 25 yuan" can be understood as "comics are 25 more expensive than stripes", which is expressed by the formula: comics = stripes +25.

Card 3 steps. Comprehensive hooded models = cartoon models+18 yuan; Cartoon = Stripe +25 replaces the cartoon in the first formula.

As follows: hooded model = striped model+25+18; The final result can be obtained by adjusting the formula: hooded model-striped model =25+ 18.

So the result is 25+ 18=43 yuan.
