Sales tax = 5%
Sales Tax = $2
⇒ 5% is equal to $2
------------------------------------------------------------
Find 1%:
------------------------------------------------------------
5% = $2
1% = $2 ÷ 5
1% = $0.40
------------------------------------------------------------
Find 100% (Cost of the meal):
------------------------------------------------------------
100% = $0.40 x 100
100% = $40
------------------------------------------------------------
Find tips:
------------------------------------------------------------
15% tips = 15% x $40
15% tips = 0.15 x 40
15% tips = $6
------------------------------------------------------------
Find total cost:
------------------------------------------------------------
Total cost = $40 + $2 + $6 = $48
------------------------------------------------------------
Answer: $48
------------------------------------------------------------
Answer: 57.266
Align all the decimal point and do the operation required.
Im not sure if you still want an answer but if you want i can give one to you sorry im late (:(
Ok to start this problem you must list two numbers that add to 14
7 and 7
9 and 5
10 and 4
6 and 8
those are the numbers that we will use for now..
Now multiply each pair of numbers and see which one equals 45
7 * 7 = 49, no
9 * 5 = 45, YES
10 * 4 = 40, No
6 * 8 = 48, No
The numbers discovered are 9 and 5
Consider, pls, this solution:
If given a equation:
-12x²+11x-3=0, then
12x²-11x+3=0
D=b²-4ac=121-12*12=-23<0
