Martiza is playing a computer game to her learn about science. her scores for six games were 11, 12,10,8,14, and 15

Points  she needs to earn on the next game = 14

Step-by-step explanation:

Martiza scores for six games were 11, 12,10,8,14, and 15.

(11+12+10+8+14+15+x)/7=12

(70+x)/7 = 12

Multiply both sides by 7

(70+x)/7 *7 = 12*7

70+x = 84

Combine the constants:

x=84-70

x = 14

Points she needs to earn on the next game = 14
