ariel has test scores of 90, 74, 82, and 90. The next test is the final exam, which counts as two tests. what score does the student need on the final exam to produce an average score of 90?

116

Step-by-step explanation:

(90+74+82+90+x)/5=90

x=450-(90+74+82+90)

x=116

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
