What is Unitary method ?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Using unitary method to solve the given problem -

It is given that a car traveled at a constant speed for 4 hours and covered 144.6 miles and also it used 12 gallons of gas to travel this distance.

It took 4 hours to travel a distance of 144.6 miles.

For 1 hour at constant speed, the car will travel 144.6/4 miles .

∴ For 1 hour at constant speed the car travels 36.15 miles.

For 12 gallons of gas, the car travels 144.6 miles.

For 1 gallon of gas, the car travels 144.6/12 = 12.05 miles

∴ For 1 gallon of gas, the car travels 12.05 miles.

Thus the car travelled a distance of 36.15 miles in 1 hour. The car travelled a distance of 12.05 miles in 1 gallon of gas.

Answer 2

Answer: 1 hour= 36.15 miles
You get this when you divide the # of miles by the # of hours

1 gallon of gas= 12.05 miles
You get this because when you want to get to 1 gallon you just divide the miles it went by the amount of gas it took to get there

during a 20%of sale,the sale price of an mp3 alarm clock was 35.96 what was the regular price of the radio

Answers

If 20% was taken off, that means that 35.96 is 80% of the original price.
35.96 = $(80)/(100)$
Now, we just need to put it into fractions, cross multiply, and divide to find the original price.
$(35.96)/(1) = (80)/(100) \$
35.96×100 = 3596
1×80 = 80
3596÷80 = 44.95
Now, to make sure, we multiply 44.95 by 20%,
44.95×0.20 = 8.99
Subtract that from 44.95
44.95-8.99 = 35.96
That is the sale price of the alarm clock.
This means that yes, the regular price of the mp3 alarm clock was
$44.95
