Solve the following problem.

if 843 units cost $16,421.40 to produce, how much does each unit cost to produce to the nearest cent?

a)19.47
b)19.48
c)20.00
d)19.50

B) 19.48.

Step-by-step explanation:

Hi, to answer this question we simply have to divide the cost of the whole production (16,421.20) by the number of units produced (843).

Mathematically speaking

16,421.40 / 843 =19.4797153

Rounded to the nearest cent:

19.4797153 = 19.48 (since the digit after the hundredth place is higher than 5)

So, the correct answer is option B) 19.48.

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
