Answer:
Shelf A = $6 ;Shelf y = $4
Step-by-step explanation:
Let :
x = cost of items from shelf A
y = cost of items from shelf B
3x + 2y = 26 - - - - (1)
2x + 5y = 32 - - - - (11)
Using elimination method :
Multiply (1) by 2 and (11) by 3
6x + 4y = 52 - - - (111)
6x + 15y = 96 - - - (1V)
Subtract (1V) from (111)
-11y = - 44
y = 44/ 11 ; y = 4
Put y = 4 in (1)
3x + 2(4) = 26
3x + 8 = 26
3x = 26 - 8
3x = 18
x = 18 / 3
x = 6
Answer: weight of elephant has smaller percent error.
Step-by-step explanation:
Percent error =
Estimated weight of elephant = 10,000 pounds
Actual weight of elephant = 12,400 pounds
Percent error of weight =
Estimated weight of hippopotamus = 2,500 pounds
Actual weight of hippopotamus = 3,600 pounds
Percent error of weight =
Since 19.35 < 30.55
hence, weight of elephant has smaller percent error.
