ANSWER
EXPLANATION
Let the number of people riding in each bus be x.
We have that 20 people are riding in 4 vans and there are x people in each van <em>(given that there is an equal number of people in each van)</em>.
This means that the product of the number of people in each van and the number of vans must be equal to the total number of people.
That is:
Solve for x:
That is the answer.
Answer:
the forth one 10√2-3√3
Step-by-step explanation:
To find the total amount Dave and Mel paid, apply the taxes to their initial purchases.
Dave paid $15 for a baseball. There was an 8% tax added to this total afterwards. To add the tax to the amount Dave paid, convert the percentage into a decimal:
Multiply the cost of the baseball by this decimal to find the tax:
Add the tax onto the cost:
Dave paid $16.20 in total for the baseball.
Mel paid $20 for a football. There is an 8% tax added to this total afterwards. We already have the decimal for an 8% tax, so we can multiply the football's cost by the decimal:
Add the tax onto the cost:
Mel paid $21.60 for the football.
Subtract the bigger cost by the smaller cost:
There is a
$5.40 difference between Dave's and Mel's purchases.
