Question 1111325
The mean height of Ana, Lucy Pearl and Tess is 66 inches.
4 * 66 = 264 is the total of the 4 girls' heights
 What is the height of Cora if the mean of the five girls is 70 inches
let c = Cora's height
{{{(264+c)/5}}} = 70

264 + c = 5(70)
c = 350 - 264
c = 86 inches, a basketball player for sure
