SYSTEM OF EQUATIONS
S+B = 17000
0.1S+0.07B=1280
Multiply the first equation by 0.1 and subtract the second equation
0.03B=420
B=14,000
S=3,000
18 - 2,3,6,8
24 - 2,4,6,8,12
HCF = 8
I think the correct answer among the choices presented above is option B. Average is the sum of all the data divided the number of data added. From the statement, we have 3 prices to be added and divided by 3. Therefore, the average is calculated as
<span>($32 + $45 + $39) ÷ 3</span>
Answer:
-2*3
Step-by-step explanation:
If she had to refund $2 for each cup (-2) and she refunded 3 cups (3) she would lose a balance of -2*3.
7.25/100 = 0.0725 => 0.0725 × 28,000 = 2,030$
2030 × 5 = 10,150$ => 28,000 + 10,150 = 38,150$
