New Year's

A shoe store had a special offer during the New Year's sale: if you buy two discounted pairs of shoes, you get the cheaper pair for 1/2 the price! Mrs. Ludmila decided to take advantage of this offer. She bought shoes for her son that were 60% off the original price of €35, and slippers for her daughter that cost €10.50 after the discount. How much did Mrs. Ludmila pay for the purchase?

Correct answer:

x =  19.25 Eur

Step-by-step explanation:

$$\begin{gathered} a=35\cdot (1-0.60)=14 \\ b=10.50 \\ a>b \\ x=a+b/2=14+10.5/2=19.25\text{Eur} \end{gathered}$$
