Answer:
Yes ,is a reasonable amount. If she has $20 she will have enough to buy the shirt
Step-by-step explanation:
we know that
The total amount is equal to the price of the shirt plus the sales tax
we have that
![100\%+4.8\%=104.8\%=104.8/100=1.048](https://tex.z-dn.net/?f=100%5C%25%2B4.8%5C%25%3D104.8%5C%25%3D104.8%2F100%3D1.048)
Multiply 1.048 by the cost of the shirt
![\$18.95(1.048)=\$19.86](https://tex.z-dn.net/?f=%5C%2418.95%281.048%29%3D%5C%2419.86)
Compare
![\$19.86 < \$20](https://tex.z-dn.net/?f=%5C%2419.86%20%3C%20%5C%2420)
therefore
Yes ,is a reasonable amount. If she has $20 she will have enough to buy the shirt
Answer:
![\$400](https://tex.z-dn.net/?f=%5C%24400)
Step-by-step explanation:
GIVEN: A hotel charges a
annual fee plus an additional
for each night you stay there.
TO FIND: average cost per night if you stay at the hotel for
nights.
SOLUTION:
Annual fee charged by hotel ![=\$10000](https://tex.z-dn.net/?f=%3D%5C%2410000)
amount charged each night we stay there ![=\$200](https://tex.z-dn.net/?f=%3D%5C%24200)
Total number of nights we stay ![=50](https://tex.z-dn.net/?f=%3D50)
Total amount paid for
nights![=50\times\$200](https://tex.z-dn.net/?f=%3D50%5Ctimes%5C%24200)
![=\$10000](https://tex.z-dn.net/?f=%3D%5C%2410000)
Total amount paid ![=\text{annual fee}+\text{total amount paid for 50 nights}](https://tex.z-dn.net/?f=%3D%5Ctext%7Bannual%20fee%7D%2B%5Ctext%7Btotal%20amount%20paid%20for%2050%20nights%7D)
![=\$10000+\$10000](https://tex.z-dn.net/?f=%3D%5C%2410000%2B%5C%2410000)
![=\$20000](https://tex.z-dn.net/?f=%3D%5C%2420000)
average cost per night ![=\frac{\text{total amount paid}}{\text{total number of nights of stay}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5Ctext%7Btotal%20amount%20paid%7D%7D%7B%5Ctext%7Btotal%20number%20of%20nights%20of%20stay%7D%7D)
putting values,
average cost per night ![=\frac{20000}{50}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B20000%7D%7B50%7D)
![=\$400](https://tex.z-dn.net/?f=%3D%5C%24400)
Hence average cost per night if we stay at hotel for
days is ![\$400](https://tex.z-dn.net/?f=%5C%24400)
5 (0) + 2y = 4
2y = 4
Y = 2
18 + 22 + 23 + 24 + 25 + 26 + 30= 168
168/7= 24
the missing number is 24
Good Luck! XD
