Answer: so F(m) because F dollars for every mph over the speed limit
so 40 dollar speeding fine so +40 
10 dollars for every mile over and m=miles over so put them all toghether and get

so if you were going 78 mph
to find the mph over you would do 78-70=8mph over so put in 8 for m and get
F(8)=10(8)+40=80+40=$120 fine for going at 78 mph

Find the difference between theproduct of 26.22 and 3.09 and the sum of 3.507, 2.08, 11.5, and 16.712. A. 47.2208   B. 58.3108   C. 4.489   D. 6.511


 26.22× 3.09   ≈  81.0198– 3.507  ≈ 7 7.5128– 2.08  ≈  75.4328– 11.5  ≈  63.9328– 16.712
≈47.2208 Your answer is A
the difference between the product of 26.22 and 3.09 and sum of 3.507, 2.08, 11.5 and 16.712

Now this looks messy, change them into numerals:
(26.22 × 3.09) - (3.507 + 2.08 + 11.5 + 16.712)
Clear the parenthesis:
81.0198 - 33.799

Answer is: A. 47.2208
