Answer:
18.18% error
Step-by-step explanation:
Use the percent error formula,
% error = | (measured - accepted) / accepted | x 100
Plug in the values we know:
% error = | (180 - 220) / 220 | x 100
% error = | - 0.18 | x 100
% error = 18.18% error

Answer:
Their weekly sales would have to be $10,000 before they can be earning the same amount for the week
Step-by-step explanation:
If they are to be earning the same thing each week, it means whatever Toni is earning is what Nicky would be earning.
We proceed by equating their earnings so we would get x;
800 + 0.07x = 600 + 0.09x
Collect like terms
800-600 = 0.09x -0.07x
200 = 0.02x
x = 200/0.02
x = 10,000
