Answer:
Step-by-step explanation:
We first need to define a couple of variables. Let s = the cost of 1 squash and z = the cost of 1 zucchini.
Now lets translate the words into algebra:
"The cost of 5 squash and 2 zucchini is $1.32" ===> 5s + 2z = 1.32
"Three squash and 1 zucchini cost $0.75" ===> 3s + z = 0.75
There are several ways to solve systems of equations. Let's use substitution. We can find what z equals in terms of s by manipulating the second equation:
3s + z = 0.75
-3s -3s
------------ -------------
z = -3s +0.75
Now lets substitute (-3s + 0.75) into the first equation for z, then solve for s:
5s + 2(-3s + 0.75) = 1.32
Can you handle it from here?
(Hint: Once you have solved for s, you can substitute that value back into either of the equations and solve for z.)
A dot plot is a type of frequency graph just like a histogram. Whereas a histogram uses 2 axes and bars to fill the frequency graph, the dot plot is only a number line with dots. A number line presents a parameter. For this problem, this is the number of books. When you ask a group of people on how many books they've read this summer, they would give a variety of numbers. These numbers are data point as listed above. If you want to see the frequency, you place a dot on top of the number every time a person answers that number. For example, 3 people said they've read 2 books this summer. So, on top of number two, you place 3 dots. Overall, you will be able to see which has the highest frequency by stacking the dots on top of each other.
The dot plot for this data set is shown in the picture.
