Step-by-step explanation:
Answer:
16 apples.
Step-by-step explanation:
Price of apples, Px=$4
Price of tomatoes, Py=$3
Ratio of their Marginal Utilities
Since Natalie’s income is $320
320 = xPx+yPy
Since x=16, Natalie will consume 16 apples.
The answer is B (Sorry for the bad handwriting.)
Hat means y + z = 180.
<span>y is thrice than z means y = 3 * z. </span>
<span>replace y with 3 * z in the equation of y + z = 180 to get 3 * z + z = 180. </span>
<span>combine like terms to get 4 * z = 180. </span>
<span>solve for z to get z = 180 / 4 = 45 degrees. </span>
<span>since y = 3 * z, then y = 3 * 45 = 135 degrees. </span>
y = 135
<span>z = 45 </span>
y + z = 180 becomes 135 + 45 = 180
<span>y = 3 * z = 135 = 3 *45 </span>
<span>solution is confirmed to be good.</span>
