Gasoline is about $2 per gallon. You use about 1 1/2 each day driving to and from work. how much budget for gasoline over the next month (about 20 workdays).
a. $40
b. $50
c. $60
d. $70
Answer: c
1. its a basic subtraction question.
(3/4)-(1/2)=1/4 you subtract because he sold it.
2. since you want to know for 20 days, how much gas you waste,
20*( 1 1/2) = 30
So , you waste 30 gallons of gas in 20 days, How much money do you spend on 30 gallons of gas.
30*($2)= $60 for 30 gallons of gas which covers 20 workdays)
To find the portion of the business Mr. Chavez still owns, we need to subtract the portion he sold to his sister from the original portion he owned.
Mr. Chavez originally owned 3/4 of the business.
He then sold 1/2 of the business to his sister.
To find the portion he still owns, we can subtract 1/2 of 3/4 from 3/4.
3/4 - 1/2 * 3/4 = 3/4 - 3/8 = 6/8 - 3/8 = 3/8
So Mr. Chavez still owns 3/8 of the business, which is equivalent to 3/4.
The correct answer is b) 1/4.
Now let's move on to the second question about the budget for gasoline over the next month when the price of gasoline is $2 per gallon.
You use about 1 1/2 gallons of gasoline each day driving to and from work, and there are about 20 workdays in a month.
To find the total amount of gasoline you will use in a month, multiply the daily usage by the number of workdays:
1 1/2 gallons/day * 20 workdays = (3/2) * 20 = 3 * 10 = 30 gallons.
Now, to find the budget for gasoline, multiply the total amount of gasoline by the price per gallon:
30 gallons * $2/gallon = $60.
So the correct answer is c) $60.
