First set up the equation equal to zero(0), the distribute from there.
Hilda bought 15.11 lb of pork.
Step-by-step explanation:
Cost of Beef that Hilda bought = 4 17/20 = 4.85 lb
Cost of the total meat she bought = 19 24/25 = 19.96 lb.
To find the number of pounds of pork she bought, subtract.
Number of pounds of pork she bought = 19.96 - 4.85 = 15.11 lb.
This question has extraneous info to trick you.
f(x) = g(x)h(x) ⇒ f'(x) = g'(x)h'(x) . Letting x = 10, we get f'(10) = g'(10)h'(10). then just plug in the values provided. g(10) and h(10) are there to throw you off, just use g'(10) and h'(10).
So f'(10), pronounced "eff prime of ten", = 0 * 35 = 0.
If the question were asking for f(10) instead of f'(10) then you would use g(10) and h(10), ⇒-4*560=90.
Answer:
C
180(.6) because 40% off is 0.4 and what is left over is 60% or 0.6. When you multiply this you get 108. 5% sales tax is a 5% increase, so multiple 108(1.05) and you get $113.40.
