A chef uses the expression 0.3n to represent the pounds of beef to use in a soup recipe for n people. The soup also has
7 fewer pounds of carrots than beef,
twice as many pounds of potatoes as beef, and
half as many pounds of onions as carrots.
How many pounds of ingredients will the chef use to make soup for 40 people?
Enter your answer in the box.
f(x) = y
f(-3) = -5
let y equal to
the total fare and x is the mile of taxi ride. so the equation is
y = 0.55x + 1.75
since susie has
$10 to spend for a taxi cab, so he can have
10 = 0.55x +
x = 15 miles of
so the system of
10 < 0.55x +
x > 2
y - 25 = 2 ( x - 10 ) should be the answer
