Answer:the average this year is $13284
Step-by-step explanation:
Engineering students at riverside college last year received, on. Average, $11,070 in scholarships and grant money. This year, the average is 20% higher. The value of the increase would be
20/100 × 11070 = 0.2 × 11070 = $2214
Therefore, the average this year would be the sum of the average last year and the value of the increase. It becomes
11070 + 2214 = $13284
Answer:
True
Step-by-step explanation:
To find the average of anything, you add their values together, and then divide that number by how many of them you added.
Here, you are trying to calculate monthly expenditure, so you add their values together (the sum of monthly expenditures) and then you divide it by how many months you used to add up to the sum (divided by the number of months).
