This is a problem in direct variation. For every five minutes that goes by, Liz utters 225 words. The general form of an equation of direct variation is
w = k x, where w is the # of words, k is the constant of proportionality and x is the number of minutes that have elapsed.
Find k by dividing 225 words by 5 minutes, to find the number of words per minute.
Next: How many minutes are there between 10:30 a.m. and 11:15 a.m.? Calculate w=kx, using your constant of proportionality, k, and that number of minutes.
$90 $27
100% ?
?=27x100 over 90(criss-cross method)
?=30% off
Solve step by step:
30 - 3 = 27
27/9 = 3
3 + 27 = 30 (Total amount)
So, each bar of candy cost $3.00
