Answer:

C

Step-by-step explanation:

When using percentages to multiply 100% is equivalent to a factor of 1, 150% to 1.5, 15% to .15, etc.

first one:

a 60% increase indicates the future yield will be 60% + 100% or 160% of the regular yield.  All you have to do is multiply the current yield by 160% or 1.6

3. same idea: the Akashi bridge is 153% of or 1.53 times the length of the Verrazano-Narrows bridge.

4. Take the difference between the two jobs  ($880.00-$790.00=$90.00) then find what $90.00 is 12% of.

.12 x WN = $90  yields   WN= $90/.12  = amount that he will have to sell.   You can check your answer by multiplying it by .12 to get $90.
