Roberto farms a tract of land that typically yields 69.6 kilograms of peas. A fertilizer manufacturer claims that its fertilizer will produce a 60% increase in the yield. What total amount of peas should Roberto expect from this tract of land if he applies the fertilizer? If necessary, round your answer to the nearest hundredth. A.111.36 kilograms
B.27.84 kilograms
C.41.76 kilograms
D.4,245.6 kilograms

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.
