Answer is $782.10
1st year —2754 ÷ 0.27 = 743.58         2754 – 743.58 = 2010.42 
2nd year— 2010.42 ÷ 0.27 = 542.81   2010.42 – 542.81 = 1467.61 
3rd year — 1467.61 ÷ 0.27 = 396.25   1467.61 – 396.25 = 1071.36 
4th year — 1071.36 ÷ 0.27 = 289.26   1071.36 – 289.26 = 782.10

Y=ab^t, 

a=2754, b=(100-27)/100=0.73

y=2754(0.73^t)

y(4)=2754(0.73^4)

y(4)≈$782.09  (to nearest cent)

MrRa [10]

Answer:

see the explanation

Step-by-step explanation:

Let

x ----> the number of hours Eli worked

y ----> the number of hours Samantha worked

we know that

Eli and they ironed 400 shirts between them

so

 ----> equation A

Samantha worked 2 more hours than Eli

so

----> equation B

solve the system by substitution

substitute equation B in equation A

solve for x

Find the value of y

substitute the value of x in equation B

therefore

The number of hours Eli worked was 6 and the number of hours Samantha worked was 8

(System of inequality word problem.)
lana66690 [7]

Answer:

C

Step-by-step explanation:

Because nintendo price=300$

He has 215$

1 chore he does=7$

Meaning if he did 10 chores he get's 70$ added so he did 10 now he has 285$ If he does 2 more chores that is 14$ more added.

So he now has 299$ so he done 12 chores and he needs 1 more dollar so if he did 1 more he gets 306$ and that was the least amount of chores he could do if he wanted 300$

And there's your answer

Hope this helps have a awesome day:)

On a bike ride, calvin starts at home and goes up a long hill for 30 minutes at just 6 mph. at the top, he turns around and ride
omeli [17]

Answer:

<u>9 mph</u>

Step-by-step explanation:

Calvin's first leg of the trip took 0.5 hr (30 minutes) at 6 mph.  That means he travelled (0.5hr x 6 mph =) 3 miles.  He travelled 3 miles on the return trip, by definition (same path home).  At 18 mph, 3 miles would take (3 miles/18 mph =) 0.1667 hours.  That makes a total of 6 miles and (0.5 + 0.1667=) 0.6667 hours.

(6 miles)/(0.6667 hours) = 9 mph is Calvin's average speed for the round trip.
