<span>Equation:
0.15x + 0.10(5-x) = 0.11*5
---
Multiply thru by 100:
15x + 10*5 - 10x = 11*5
---
5x = 5
x = 1 liter (amt. 15% oj needed)
----
5-x = 4 liters (amt of 10% oj needed)

Answer:
y = -1/2
Step-by-step explanation:
−7⋅
Membership is discounted $2 for first month
c=cost of one month
d=discount=$2
x=# of months
xc - 2= total cost
x for 1 month is 1, c is always 12, -2 is constant
1 x(12) - 2=10 for first month
8 months
8c -2=total cost for 8 months
8 x 12 - 2= 94 for 8 months

Answer:
$6.25
Step-by-step explanation:
2000ml = 2 litres
2.5L - 2L = 500ml
So now we know that without the 500ml, it is 5 dollars.
Find out how much 500 ml cost.
2000ml = 5.00
1ml = 5.00 ÷ 2000 = 0.0025
500ml = 0.0025 x 500 = 1.25
2L + 500 ml = 2.5L (which 2.5L costs 6.25)
