is the inequality that describes this problem
Given that Travis can spend no more than $125.75 every month
To find: linear inequality that describes the problem
Let the amount spent on movies = x dollars
Given that Travis decided to spend 4.3 times as much money on video games as he spends on movies
Amount spent on video games = 4.3 (amount spent on movies)
Amount spent on video games = 4.3x
Travis can spend no more than $125.75. That is, he can spend less than or equal to $125.75
<em><u>Thus, the inequality representing the situation is:</u></em>
Thus the required inequality is found
Answer:
Randy is 48 years old
Sandy is 12 years old
Todd is 27 years old
<em></em>
Step-by-step explanation:
Given
Represent their ages with the first letters of their names:
Required
Determine their individual ages
We'll solve the above equations using substitution method of simultaneous equations
Substitute 15 + S for T and 4 * S for R in
This gives:
Collect Like Terms
Divide through by 6
<em>This implies that Sandy is 12 years old</em>
Substitute 12 for S in and
<em>This implies that Randy is 48 years old and Todd is 27</em>
