Works in a clothing store where she earns 140 per day plus 14% of her sales she works in weekends. Assuming she sells the same amount on both days, how much will her sales have to be each day in order to earn at least 500 over the weekend ?

She would need to sell atleast $786 per day.

Explanation:

=

*balance and subtract*

-280. -280

.28x = 220 *divide*

0.28x/0.28 = 220/0.28

= $786

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

probability for j is 1/4

while

a is 1/6
