Answer:
b. 180 is the answer
Step-by-step explanation:
5*1 = 5
5*3 = 15
5*5 = 25
5*7 = 35
5*9 = 45
5*11 = 55
None of them involve 0's
The equation is
y = (-1/2) * x + 9/2
400/12 = # of dozen needed
.89 * # of dozen needed
400/12=33.33 need 34 dozen
.89*34=$30.26
To the nearest tenth : 32.7
To the nearest hundredth : 32.70
Whole Number : 33
