W + y = 30......w = 30 - y
11.95w + 12.50y = 364.55
11.95(30 - y) + 12.50y = 364.55
358.50 - 11.95y + 12.50y = 364.55
-11.95y + 12.50y = 364.55 - 358.50
0.55y = 6.05
y = 6.05 / 0.55
y = 11 <=== there were 11 yellow sweatshirts sold
w + y = 30
w + 11 = 30
w = 30 - 11
w = 19 <=== there were 19 white sweatshirts sold
Answer:
it is congruent
Step-by-step explanation:
There are 3 more dots above the 13 than are above the 12, so the appropriate choice is ...
... A. 3
If $1 is 5%, 100% would be $1 times 100/5= $1 times 20 = $20
75 additional minutes were used
$61.20-$49.95=$11.25
$11.25/$0.15=75 additional minutes
