The second or third one I believe
m = (-1 - 4) /(2-3) = -5/-1 = 5
slope = 5
passing (3, 4)
y = mx + b
4 = 5(3) + b
4 = 15 + b
4 -15 = b
-11 = b or b = -11
answer:
equation
y = 5x - 11
So he is paid 46.5 flat every day
he earns 5% of each smart phone he sells
at the time of the problem, smart phones sell for 70 so he earns 5% or 70 or 5/100 of 70 or 1/20 of 70 or 70/20 or 7/2 or 3 and 1/2 or $3.50 per phone he sells
so pay must be at lease 150 so
pay=46.5+ (# of phones times 3.50)
150<u><</u>46.50+(number of pones times 3.50)
solve for number of phones
subtract 46.5 from both sides
103.5<u><</u>(number of phonest imes 3.5)
divdie both sides by 3.5
29.57<u><</u>number of phones
round up since can't sell a fraction of a phone
30
he has to sell at leas 30 phones
