A pound of blueberries costs $3.98 and a pound of clementines costs $2.49. What is the combined cost of 2 pound of blueberries and 3 pounds of clementines? Explain how you got your answer.

$15.43

Step-by-step explanation:

Basic algebra

Let's ask ourselves what we need in order to solve this problem.

We need the following:

- How many pounds of blueberries and clementines we have

-How much does each pound of blueberries and clementines cost

Well, the question provides us with the information for the second bullet point. Each pound of blueberries cost $3.98 and each pound of clementines cost $2.49.

And then we realize that the question also provides us info for the first bullet point. We want 2 pounds of blueberries and 3 pounds of clementine.

So let's map it out

We want the cost of 2 pounds of blueberries where each pound of blueberries is $3.98

And we want the cost of 3 pounds of blueberries where each pound of blueberries is $2.49

Our answer is 2 x 3.98 + 3 x 2.49 = $15.43

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
