Answer:

see explanation

Step-by-step explanation:

The mean of a set of data is calculated using

mean = \frac{totalscore}{count}, that is

\frac{5.2+8.3+8.5+7.7+7.8+y}{6} = 7.1

37.5 + y = 7.1 ( multiply both sides by 6 )

37.5 + y = 42.6 ( subtract 37.5 from both sides )

y = 5.1

Mademuasel [1]
Given:
buy a house in 9 years.
Estimated cost of the house = 175,800
down payment = 20%

47,466 / 108 = 439.50 savings per month.
