58. 01. A person spent one coin to buy a loaf of bread and a bottle of kvass (a drink). When prices increased by $20 \%$, this coin was only enough to buy half a loaf of bread and a bottle of kvass. Try to determine, if prices increase by another $20 \%$, whether this coin would be enough to buy just a bottle of kvass.
58.01. Ans: Enough. The prices of gas are $x^{1} \mathrm{j} y$, then
$$
\begin{array}{l}
x+y=1, \\
1.2(0.5 x+y)=1 .
\end{array}
$$
The price is
$$
\text { (1.2) } y=1.44 y \text {. }
$$

H J $1.44 y<1$, so enough to head - Stankebis.
