通过分析，发现销售量y对奶茶的价格x具有线性相关关系．

（Ⅰ）求销售量y对奶茶的价格x的回归直线方程；

（Ⅱ）欲使销售量为13杯，则价格应定为多少？

注：在回归直线y= $\hat{b}x+\hat{a}$ 中， $\hat{b}=\frac{{{\displaystyle \sum }}_{i=1}^n{x}_i{y}_i-n\overline{x}\overline{y}}{{{\displaystyle \sum }}_{i=1}^n{x}_i^2-n{\overline{x}}^2}$ ， $\hat{a}$ = $\overline{y}$ ﹣ $\hat{b}\overline{x}$ ． ${\displaystyle \sum }_{i=1}^4{x}_i{}^2=5^2+{5.5}^2+{6.5}^2+7^2$ =146.5．
