What is the value of x in the equation 0.2(x + 1) + 0.5x = –0.3(x – 4)?
Leokris [45]
 0.2(x + 1) + 0.5x = -0.3(x - 4) 

0.2x+0.2+0.5x=-0.3x+1.2

 
 

0.7x+0.2=-0.3x+1.2 

0.7x=-0.3x+1.2-0.2 

0.7x=-0.3x+1 

0.7x+0.3x=1 

x=1

Answer:

a. 90 pack

b. $0.27

c. $0.18

d. $0.21

e. 60 pack

Step-by-step explanation:

a. i think  the 90 pack container should be having least unit rate per pack,as purchasing in bulk amount the cost of a unit should be reduced to some amount which is must to lure the customer to purchase in bulk amounts.

b. unit price = total cost of container ÷ number of individual units inside it

for 20 pack, unit rate = 5.49÷20 = $0.27

c. for 60 pack, unit rate = 10.97÷60 =$0.18

d. for 90 pack, unit rate = 18.95÷90 =$0.21

e. ∴ the 60 pack container has the least unit rate per pack which is in contrary with our expectation of 90 pack to be lowest expecting bulk order.
