Carlos rented a truck for one day. There was a base fee of $19.99, and there was an additional charge of 86 cents for each mile

NeX [460]

Answer: 211 miles

Step-by-step explanation: An equation for this could be:

base fee + additional charge (miles driven) = total charge

19.99 + 0.86(x) = 201.45

0.86(x) = 201.45 - 19.99

0.86(x) = 181.46

x = $\frac{181.46}{0.86}$ = <em>211 miles</em>

slava [35]

Answer: $\frac{1}{3}\ s$

Step-by-step explanation:

Given

Distance traveled is $s=30t^2+440t$

for s=150 ft

$\Rightarrow 30t^2+440t=150$

$\Rightarrow 30t^2+440t-150=0\\\Rightarrow 3t^2+44t-15=0\\\Rightarrow (3t-1)(t+15)=0\\\Rightarrow t=\dfrac{1}{3}\ s$
