Answer:
$10.80
Step-by-step explanation:
$2.40 + $2.80(3)
$2.40 + 8.40
An interval scale has measurements where the difference between values is meaningful. For example, the year 0 doesn’t imply that time didn’t exist. And similarly, a temperature of zero doesn’t mean that temperature doesn’t exist at that point. Arbitrary zeros (and the inability to calculate ratios because of it) are one reason why the ratio scale — which does have meaningful zeros — is sometimes preferred.
Answer:
Andy ate 41 hot dogs
Barry ate 36 hot dogs
Carl ate 26 hot dogs
Step-by-step explanation:
Let the quantity of hot dogs eaten by Andy, Barry and Carl be A, B and C respectively.
Andy ate 5 more than Barry =>
A = B + 5. (Equation i)
Carl ate 10 less than Barry =>
C = B - 10. (Equation ii)
The three atr the total or 103 hot dogs.
ie. A + B + C = 103 (Equation iii)
From i and ii, substitute (B + 5) for A and (B - 10) for C in equation (iii)
(B + 5) + B + (B - 10) = 103
B + 5 + B + B - 10 = 103
B + B + B + 5 - 10 = 103
3B - 5 = 103
3B = 103 + 5
3B = 108
B = 108/3
B= 36
From equation (i)
A = B + 5
A = 36 + 5
A = 41
From equation (ii)
C = B - 10
C = 36 - 10
C = 26
Andy ate 41 hot dogs
Barry ate 36 hot dogs
Carl ate 26 hot dogs
