Answer:
children = 172 adults = 190
Step-by-step explanation:
x= 172 y=190
1.5x+4y = 1018
x+y=362
4x+4y=1448
-1.5x-4y=-1018
2.5x=430
x=172
1.5(172) + 4y =1018
258 + 4y = 1018
4y = 760
y = 190
Answer:
Pretty sure it would be 3.5 or 3.6 somewhere in that zone :)
Answer:
70
Step-by-step explanation:
to solve : start wit the inside brackets first
10 [25-{8-6 (16-13)}÷5 start 16-3
10[25-{8-6(3)}÷5 then multiply 6 and 3
10[25-{8-18}]÷5 then subtract 8-18
10[25-(-10)]÷5
10[25+10)÷5 add numbers inside brackets
10×35÷5=70 multiply and divide

Answer: C) 45 dollars</h3>
========================================================
Explanation:
x = sticker price, which is some number larger than 9 (otherwise the store loses money)
x-9 = profit made per speaker
To get the gross margin percentage, we divide the profit over the sales (aka revenue). So we'll divide (x-9) over x
The expression (x-9)/x represents the gross margin in decimal form. Set this equal to 0.80 and solve for x
-----------------
(x-9)/x = 0.80
x-9 = 0.80x
x-0.80x = 9
0.20x = 9
x = 9/0.20
x = 45
The sticker price is $45
-------------------
If the sticker price is $45 per speaker, then the store owner gets 45-9 = 36 dollars in profit per speaker sold. The gross margin would be (profit)/(sales) = 36/45 = 0.80 = 80%
In other words, 80% of the revenue is profit (the remaining 20% is costs or expenses).
