b= 9

3) for you party you purchased ballons for $.79 each. You spent a total of $11.85. Write an equation and estimate the number of balloons purchased,

**bobpursley**, Thursday, October 13, 2011 at 8:48pmyes, however, most people use estimate to estimate, not use a calcuator. Examples:

estimate 227 divided by 23: estimate (mine) 10

estimate 333 times 14: my estimate 3330+1300=4600

Estimate usually means "approximately", and estimates are results of mental math, not calculators.
