Answer:
yes
Step-by-step explanation:
The constant ratio (23 mi)/(1 gal) tells you the number of miles is a linear function of the number of gallons.
miles = (miles/gallon) × gallons
miles = constant × gallons . . . . . a linear function of gallons
90 is the outlier
for future reference, outliers are numbers much larger or much smaller than the other numbers in a set
for example
2,3,4,21,6
or 90,87,94,12,99
The first discounted price is given through the equation,
discounted price = ($3.45)(1 - 0.20) = $2.76
Then, due to the privilege of being a Coles-Myer discount card holder, another 7.5% discount is given. Such that the final price would be,
final price = ($2.76)(1 - 0.075) = $2.553
The total amount saved up is equal to,
$3.45 - $2.553 = $0.897
It’s definitely E. I say this because there is no correct answer.
