Answer:
8 1/4 inches
Step-by-step explanation:
(3 1/4 - 1/4) + (5 1/2 - 1/4) = 3 + 5 1/4 = 8 1/4 . . . inches
To solve the problem we will find the number of videos bought by Jerome and the total cost of all the videos.
The system of equations that model this information are:
- 15 = x + y
- 164 = 18x + 9y.
<h2>Explanation</h2>
Given to us
- Total amount spent by Jerome = $164
- Total videos bought by Jerome = 15
- Number of classic videos bought = y
- Number of new release videos bought = x
- Cost of a classic video = $8
- Cost of a new release video = $19
<h3>Total cost of all new release videos</h3>
= Number of new releases bought x Cost of a new release video
<h3>Total cost of all classic videos</h3>
= Number of classic videos bought x Cost of a classic video
<h2>Total videos bought by Jerome</h2>
Total videos bought by Jerome
= Number of new releases bought + Number of classic videos bought
15 = x + y
<h2>Total amount spent by Jerome </h2>
Total amount spent by Jerome
= Total cost of all new release videos + Total cost of all classic videos
$164 = 19x + 8y
164 = 19x +8y
Hence, the system of equations that model this information are:
- 15 = x + y
- 164 = 18x + 9y.
