Answer:
700 apples
Step-by-step explanation:
Let
x = Total number of apples in the cart
Percentage of apples sold = 40%
Number of apples sold = Percentage of apples sold * Total number of apples in the cart
= 40% * x
= 0.4 * x
= 0.4x
Number of apples left in the cart = 420
Total number of apples in the cart = Number of apples sold + Number of apples left in the cart
x = 0.4x + 420
x - 0.4x = 420
0.6x = 420
x = 420/0.6
x = 700
x = Total number of apples in the cart = 700
Lawrence started with 700 apples

Answer:
The rate of change in the submarine's elevation is 26.0 feet per second.
Step-by-step explanation:
She begins 151 feet below sea level
Thus, her initial point is y₁ = 151 feet below sea level
i.e. at t₁=0 seconds, y₁ = 151 feet below sea level
After descending for the 3 seconds, she is 229 feet below sea level.
Thus, her second point is y₂ = 229 feet below sea level after 3 seconds
i.e. at t₂=3 seconds, y₂ = 229 feet below sea level
The rate of change is basically the slope. Thus, the rate of change can be obtained by taking the slope.
slope = rate of change = (y₂ - y₁)/(t₂ - t₁)
= (229 - 151) / (3 - 0)
= 78/3
= 26.0
Therefore, the rate of change in the submarine's elevation is 26.0 feet per second.
