log4 both sides

log4[4^(x + 3)] = log4(7)

(x + 3) × log4(4) = lg7/lg4

The following equation: C=43x+14100gives the total cost, in dollars, to produce x units of a product at a factory. If the monthl

Masja [62]

We have

C is the cost

x is the units of a product at the factory

C= 35170

we need to find the value of x

The equation given is

$C=43x+14100$

so we have the value of C, so the equation if we substitute the value of C is

$35170=43x+14100$

we need to isolate the x

$\begin{gathered} 35170-14100=43x \\ 21070=43x \\ x=\frac{21070}{43} \\ x=490 \end{gathered}$

In that month,490 units can be produced for $35170.
