1. is the area under the curve to the left of , which is a trapezoid with "bases" of length 2 and 5 and "height" 0.2, so
2. Find the area under the curve for each of the specified intervals:
(triangle with base 2 and height 0.2)
(triangle with base 1 and height 0.4)
(trapezoid with "bases" 0.2 and 0.4 and "height" 2)
(trapezoid with "bases" 0.1 and 0.3 and "height" 2)
The correct answer should be 2 & 1/2 batches
2/7 + 2/7 is 4/7 and half of a batch would bring it to 5/7
Multiply everything if not that than add
