Answer:
James answered 51 questions correctly.
Step-by-step explanation:
1) Slide the decimal 2 places to the left in the percentage (85% = .85)
2) Multiply total by new decimal (60 x .85)
3) All done! (51)
Keep in mind that 100% is just 1 whole. Therefor 85% of one whole is .85. In this problem, 60 represents our whole.
Likely
$10000 Total cost to transport 14 tons
The total cost C(S) = $6500 + ($250/ton)S. <em>This is a linear function with initial value $6500 and slope $250/ton.</em>
C(14) = $6500 + ($250/ton)(14) = <em>$10000 = Total cost to transport 14 tons</em>
128
32/0.25=128
