First, we divide the amount of tip which is $16 by the amount that is used to pay the food bill which is $80. Then, multiply the quotient by 100%. Mathematically,
($16 / $80) x 100% = 20%
Thus, you left 20% of the food bill for the tip.
Answer: (2,8), because the graph of the two equations intersects at this point.
Step-by-step explanation: Got u. it's right 1000%
Those ratios are not equivalent because 240 divided by 16 is 15 and 560 divided by 28 is 20.

can be simplified to:

Make them have common denominators so:

Simplify:

I don't think you can simplify that fraction further so that's the answer.
Answer:
30
Step-by-step explanation:
100%-40%=60%
but 50 is half of 100 you half 60% to 30 people
