Answer:
$5,333.33
Step-by-step explanation:
If the a month spent on rent is a percentage of the monthly budget of the Fernando family, it means that the product of the percentage and the monthly budget gives the amount spent on rent.
Let the monthly budget be T (measured in $). Given that the family spends $800 per month on rent and this is 15% of their monthly budget, it means that
15% * T = 800
T = 800/15%
= 800 * 20/3
= $5,333.33
The family's monthly budget is $5,333.33
Answer: the remaining credit after 79 minutes of call is $15.52
Step-by-step explanation:
let x represent the number of minutes of call.
Let y represent the remaining credit after x minutes of call.
If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be
Slope, m = (17.2 - 19.84)/(65 - 43)
m = - 2.64/22 = - 0.12
The equation of the straight line can be represented in the slope-intercept form, y = mx + c
Where
c = intercept
m = slope
To determine the intercept, we would substitute x = 65, y = 17.2 and m = - 0.12 into y = mx + c. It becomes
17.2 = - 0.12 × 65 + c
17.2 = - 7.8 + c
c = 17.2 + 7.8
c = 25
The linear function becomes
y = - 0.12x + 25
Therefore, the remaining credit after 79 minutes of call is
y = - 0.12 × 79 + 25
y = - 9.4 + 25
y = 15.52
Break the problem down and replace the x with the given number when you do that it’ll show you the answer to the question you just need to use key details in it to get the exact answer
