Answer:
a-135 hot dogs and 245 sodas were sold.
Step-by-step explanation:
Our equations are:
1.25h + 0.75s = 352.50
h + s = 380
Let's use substitution to solve for this system. In the second equation, let's write h in terms of s:
h + s = 380
h = 380 - s
Now, let's plug in 380 - s for h in the first equation:
1.25h + 0.75s = 352.50
1.25(380 - s) + 0.75s = 352.50
We can now solve for s fairly easily:
1.25(380 - s) + 0.75s = 352.50
475 - 1.25s + 0.75s = 352.50
0.5s = 122.5
s = 245 sodas
We can already see which answer choice will match: A, and that is our answer.
Move all terms to the left side then set equal to 0. then set each factor equal to 0. k=-1, -5
Answer:
(2,3)
Step-by-step explanation:
I did this by using the equation that was given. y=x+1.
This mean that the starting point would be the coordinate (0,1) and the x is the slope, which means that from coordinate (0,1) I will go up one and one to the right until I intersected with coordinate (2,3).
15% * 375 = 0.15*375 = 15*375/100=56.25
