Please help me fill in the blank spaces (!The blank spaces are for the UNIT RATE!)

3) 0.8 pencils per dollar

Step-by-step explanation:

All of the questions follow the same procedure, so I'll give you the answer just for the first question shown, question 3. Firstly, what is a unit rate? A unit rate is a rate for one of something. An example of a unit rate is "5 miles per hour", where "5 miles" is the rate, and "hour" is the something.

Number three: 8 pencils for 10 dollars. The question is asking: "How many pencils do you get for one dollar?". We can find this through division:

> (8 pencils) / (10 dollars)

> 8/10 pencils per dollar

> 4/5 pencils per dollar

The final number in decimal form, 0.8 pencils per dollar, is the answer to number 3.

Now try number 4. The correct answer for number 4 is about 1.55 batteries per dollar. Did you get this same answer? If not, comment on my answer, and I may be able to try and help you through another problem.

Have a good day!

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
