2a+1b=27.50
4a+2b=59.50
Multiply first equation by -4 and the second by 2 so you can drop off the a values then add the equations together. Then solve for b. You should get b=6.
Then plug b into one of the original equations and solve for a and you should get 10.75
So a plate of spaghetti is $10.75 and a salad is $6.

Answer:
19 or 21.
Step-by-step explanation:
I swear.
5 + 5 = 10
10 + 5 = 15
15 + 4 = 19
________________
9 + 9 = 18
18 + 10 = 28
28 - 5 = 23
There are two nines so
23 - 2 = 21
Answer:
Vertical
Step-by-step explanation:
<u>Answer-</u>
<em>The exponential function that satisfies the given conditions is 
</em>
<u>Solution-</u>
This can be represented as exponential decreasing function,
Where,
-
a = starting amount = 67
- r = rate = 0.47% = 0.0047
- t = week
Putting the values,
Therefore, the exponential function that satisfies the given conditions is
