When I took algebra in high school we were given problems that involved trains or planes leaving a place, traveling at a rate of speed and arriving at a destination. The fact that I had never been on either didn't prevent me from solving the problem. Looks to me as if the students are expecting Kitna to dumb down the lesson before they are willing to put forth an effort or they have been conditioned not to think. The mere mention of calculators tells me that the later is the case and that whoever is responsible for the calculators is a product of a dumbed-down education. Btw, the answer is $13.65....without even a pencil or paper, much less a calculator and I've never been in a taxicab also.
8 miles traveled. $1.85 plus .40 per quarter mile. $1.85 + $1.60 per mile $1.60 x 8 (miles) = $12.80 + $1.85 = $14.65
Perhaps, just perhaps, you should buy one and use it. It's $14.65. It certainly seems plausible for a kid not to understand what a flat fare entails. Broken educational system? No doubt.
I shudder when I hear mention of calculators in basic algebra. Hell, I remember having to calc betas in college by hand. That prof hated the world... The kids dont understand the why without working it out on paper.
