Answer:
25 months
Step-by-step explanation:
when the rent, y = 0, we have,
y = -200.22x + 5014.20
y = 0
0 = -200.22x + 5014.20
200.22x = 5014.20
x = 5014.20 ÷ 200.22
x = 25.0434
x = 25(appx.)
Sorry, I don't know what you mean by interpolation and extrapolation:(
Answer:
$87.60
Step-by-step explanation:
Assuming that mary is on a fixed income rate, we can calculate that Mary is making approximately $5.84 per week.
17.50 / 3 = 5.833333.... -> <em>5.84</em>
Now we multiply this number by 15 to get the amount of money she saves over this time.
5.84 * 15 = <em>87.6</em>
<em>So, we can see that Mary has saved $87.60 in 15 weeks.</em>
