Let S be the amount in a savings account.
Let m be the number of months.
General equation
S = 132 + 27m
Specific question
July is the 7th month of the year including both January and July.
S = 132 + 7*27
S = 132 + 189
S = 321
Reasonableness?
Good question. You could estimate an answer.
Start with 150 dollars and say that you add 25 a month.
7 * 25 = 175
S = 150 + 175 = 325 All of this was done in my head. Since the exact answer obtained using the formula is 321, I think that's pretty reasonable using my estimate is a guide.
Answer:
4
Step-by-step explanation:
3^2=9
-2 times 3 = -6
9-6+1=4
Answer:
m ∈ R
Step-by-step explanation:
- 1,84 - 2,3m = - 2,3(m + 0,8)
- 1,84 - 2,3m = - 2,3m - 1,84
m ∈ R
