: 1) Tamara traveled north in her car on a straight, one-lane road for 0.25 mile.
: When she stopped at the end of the road, her car faced south.
: How could this be?
She was backing up; get it, Matt?
: 2)Katrina went bowling with her friends 4 times. Each time her bowling score
: increased by 8 points. If the total of her four scores is 300 points, what was
: her score in each of the four games?
Hmmm...5th grade, eh?
Let the low game (1st one) = x; then:
x + x+8 + x+16 + x+24 = 300 ; follow that?
4x + 48 = 300 ; 4x = 252 : subtract 48 from each side
so x = 252/4 = 63 ; still with me?
This makes her scores 63, 71, 79 and 87; 63+71+79+87=300 : ok, Matt?
I'm assuming you've been exposed to a bit of algebra; have you?
