Answer:
17 is 35 degrees and 18 is 43 degrees
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.

Exact form: b= 22/5
Decimal form: b= 4.4
Mixed number form: b= 4 2/5
I think we need a picture to solve that
1. meters
2(a). mm
2(b). cm
3. Gram
4(a). g
4(b). kg
4(c). g
5. Liter
