2x^2+2x-14x-7
Answer: 2x^2-12x-7
Answer:
9
Step-by-step explanation:
If the mark up is 75% then the price of a necklace is 56.7
the least they want to profit is 500
so the answer should be at least 9, because the price is over 55, which would be 550 if multiplied by 10
You should include a passage because without it there is no sense in this
Answer:
7*1/7=1
Step-by-step explanation:
The linear equation that represents the relationship between earnings and tips will be y = 0.75x + 50.
<h3>What is a linear equation?</h3>
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Working as a waitress is Amanda. She receives $50 every day in addition to 75% of the tips her clients leave.
Let 'x' be the tip amount and 'y' be the total earning.
y = 0.75x + 50
Check:
At (20,65), then we have
65 = 0.75(20)+50
65 = 15+50
65=65
At (50,87.5), then we have
87.5 = 0.75(50)+50
87.5 = 37.5+50
87.5=87.5
At (100,125), then we have
125 = 0.75(100)+50
125 = 75+50
125=125
