A family went to a restaurant for dinner. The subtotal for the meal including tax is $65.90. The family decided to leave a 20% tip. How much did the family pay total including tip?
Solution 1
Answer:
$79.08
Step-by-step explanation:
Find 20% of 65.90. 20% as a decimal is 0.20. Multiply 0.2 and 65.90.
65.90 x 0.20 = 13.18
Add 13.18 to the original price.
13.18 + 65.90 = 79.08

Answer:
(0.5, 1.3)(0.5, 1.3)
Step-by-step explanation:
Given equations are:
As we can see that the given equations are linear equations which are graphed as straight lines on graph. The solution of two equations is the point of their intersection on the graph.
We can plot the graph of both equations using any online or desktop graphing tool.
We have used "Desmos" online graphing calculator to plot the graph of two lines (Picture Attached)
We can see from the graph that the lines intersect at: (0.517, 1.267)
Rounding off both coordinates of point of intersection to nearest tenth we get
(0.5, 1.3)
Hence,
(0.5, 1.3) is the correct answer

Step-by-step explanation:
dy = the change in y-values = –2–3 = –5
dx = the change in x-values = 6–(–4) = 6+4 = 10
m = Dy/Dx = –5/10
m = –½
Answer:
It is a 40% increase
Step-by-step explanation:
So first of all the formula is
New-old/old
Or rate of change/ original
SO th new is 350
THe old is 210
350-210=140
140/350 which is old is 2/5
2/5 is 40 percent
So 40 percent increase
Answer: 66.66% rise
Step-by-step explanation:
350-210=140
140/210 =2/3
66.6% rise
