x=4
Step-by-step explanation:
OKOK
A salesperson averaged $120 per 10 days sooo 120/10 is 12 so about 12 per day
So,
You guess the amount that could make up a number around 150or 160
So 12 x3 = 36 + 120=156 hallelujah!
So, 3 more days until she can average $160 in order to bring her overall average to 150%.....
Hope this helps. :::)))))

Answer:
3 minutes
Step-by-step explanation:
Let x represent Alysha's time to drive home from the market.
Speed and time are inversely proportional to each other (for the same distance), so we have ...
(walking speed)(walking time) = (driving speed)(driving time)
5(x +21) = (8·5)(x)
x +21 = 8x . . . . . . . . . divide by 5
21 = 7x . . . . . . . . subtract x
3 = x . . . . . . .divide by 7
It takes Alysha 3 minutes to drive home from the market.
To find the difference you would need to make the denominator equal so I changed it to 15 and the difference would be 7/15
