3 hours x 60min/hr = 180 minutes
45 x 4 = 180 minutes
15 x 4 = 60 sandwiches
Answer:
20
Step-by-step explanation:
Multiples of 5 are: 5, 10, 15, 20, 25, 30, 35, 40, etc. Each multiple is created by multiply 5 times some other number.
Area of each of the tiles = (2.5 * 6) inches^2
= 15 inches^2
Now we have to get down to the case of the backsplash
1 feet = 12 inches
Then
Length of the back splash = 8 feet
= (8 * 12) inches
= 96 inches
Height of the back splash = 2.5 feet
= (2.5 * 12) inches
= 30 inches
Then
Area of the back splash = ( 30 * 96) inches^2
= 2880 inches^2
So
The number of tiles required to fit in the back splash = 2880/15
= 192
So 192 tiles will be required to fit in the back splash. I hope the procedure is clear enough for you to understand.
You have to add 15+30+12+18...
So she started with $75.
Hoped I helped!
Good luck!
9.95×4=39.80
12.95×2=25.90
15.95×2=31.90
39.80+ 25.90+31.90=97.60
97.60×.18=17.56
97.60+17.56=$115.16 without tax and 18% gratutity
