What will be the annual salary for a mechanic who works 40 hours per week for 52 weeks a year and makes $25.21 per hour
dalvyx [7]
40 hours * 52 weeks = 2080 hours total worked that year. 

2080 hours * 25.21 paycheck = 52,436.80

In reality you would have to subtract out holidays, any vacation, any sick days and taxes. All of that information varies by location and company.

One Friday night, two large groups of people called Weston Taxi Service. The first group requested 2 sedans and 1 minivan, which
muminat

Answer:

Sedan: 4 passengers

Minivan: 6 passengers

Step-by-step explanation:

We can write the following system of equations:

\begin{cases}2s+1m=14 \\2s+2m=20\end{cases}, where s represents the number of people a sedan can seat and m represents the number of people a minivan can seat.

Subtracting the first equation from the second, we have:

2s+2m-(2s+1m)=20-14,\\\\m=6

Now plug in m=6 in any of the equations to solve for s:

2s+1(6)=14, \\2s=8, \\s=4

Verify that the solution pair (4, 6) works:

2(4)+1(6)=14\: \checkmark \\2(4)+2(6)=20 \: \checkmark

Therefore, a sedan can hold 4 passengers and a minivan can hold 6 passengers.
