Answer:
$11.10 per gallon.
Step-by-step explanation:
There are 4 quarts in a gallon so the cost of a gallon of oil currently is 1.85×4=$7.40
If the gallon price of oil goes up 50% then our answer is: 7.40×==11.1
The price of oil in March will be $11.10 per gallon.
Answer:
$6.83
Step-by-step explanation:
First calculate the before-tax total amount:
$0.75 + $0.75 + $0.75 + $4.25, or
3($0.75) + $4.25 = $2.25 + $4.25 = $6.50 (total before tax)
The before-tax total PLUS the 5% tax comes to:
$6.50 + 0.05($6.50) = $6.50 + $0.33 = $6.83
Solution:
we are given that
In a class, every student knows French or German (or both).
15 students know French, and 17 students know German.
Suppose there are x student who knows both French and German.
Then Total number of student in the class will be
But to guess the largest possible number of student in the class we can assume x=0
Hence the largest Possible number of Student in the class=32
