S + c + b = 52
c = s + 2
b = c + 9.....b = s + 2 + 9....b = s + 11
s + (s + 2) + (s + 11) = 52....combine like terms
3s + 13 = 52
3s = 52 - 13
3s = 39
s = 39/3
s = 13 <=== there were 13 strawberry bagels
c = s + 2
c = 13 + 2
c = 15 <=== there were 15 cinnamon-raisin bagels
b = c + 9
b = 15 + 9
b = 24 <=== there were 24 blueberry bagels
Answer:
Their expenses and sales will both equal at 200 ounces.
Step-by-step explanation:
This can be determined using the break-even point in ounce formula as follows:
Break even point in ounce = Fixed cost / Contribution per ounce
Where;
Fixed cost = Advertising = $600
Contribution per ounce = Selling price per ounce - Cost per ounce = $4 - $1 = $3
Substituting the values into equation (1), we have:
Break even point in ounce = $600 / $3 = 200 ounces
Therefore, their expenses and sales will both equal at 200 ounces.
15/30=2/4
you divide 15 by 7.5=2, and 30 by 7.2 which equals 4
2x²+5=13
subtract the 5 on both sides
2x²=8
divide by 2 on both sides
x²=4
put each side under the radical because of the exponent 2
√x²=√4
the radical cancels out the exponent 2; √4 = 2
x=2
