Answer:
20
Step-by-step explanation:
To solve this you have to make a system of equations.
Since the father and son's age sum up to 60, the first equation will be:
f + s = 60
Secondly, since the father's age is 5 times the age of the son 6 years ago the equation will be:
6 - (5s) = f
Now, you have to solve the first equation to let it equal to s
f + s = 60
f = 60 - s
Plug in
6 - 5s = 60 - s
+s +s
6 - 4s = 60
-6 -6
---------------------
-4s = 54
----- -----
-4 -4
s ≅ 14
14 + 6 = 20
10+18=28
17+11=28
OR
2x=28 where x=14
4x where x=7
Answer:
$105.20
Step-by-step explanation:
Given that :
Cost of materials = $62.30
Cost of booth = $25 / month
Price per bracelet = $5.50
Profit of 35 bracelet is sold next month =?
Profit = Revenue - Expenses
Revenue = $5.50 * 35 = $192.50
Expenses = $25 + $62.30 = $87.30
Profit = $192.50 - $87.30
= $105.20
The easiest way would be adding 76
The answer is 15 : 5
because In mathematics, a ratio is a relationship between two numbers indicating how many times the first number contains the second. For example, if a bowl of fruit contains eight oranges and six lemons, then the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).
And you said girls : boys
That means 15 : 5 or 15 to 5
