A faucet is used to add water to a large bottle that already contained some water. After it has been filling for 55 seconds, the gauge on the bottle indicates that it contains 1919 ounces of water. After it has been filling for 1111 seconds, the gauge indicates the bottle contains 3737 ounces of water. Let y be the amount of water in the bottle x seconds after the faucet was turned on. Write a linear equation that relates the amount of water in the bottle, y, to the time x.

Teachers at Price Middle School are planning a birthday party for the principal. Planners estimated that 42 slices of cake would be needed. In fact, only 30 slices of cake were eaten. What was the percent error in the estimate of how much cake was eaten?A student solved the problem and showed his work below. What was his error?|42-30|---------- (100) = 6% 421 The planners did not use the absolute error in the ratio.2 The planners compared the absolute error to the approximate value.3 The planners did not multiply by 100 to get the percent.4 The planners divided incorrectly and got the wrong answer.
