• the table shows the relationship between time spent running and distance traveled. a 2-column table with 5 rows. the first column is labeled time (minutes) with entries 1, 2, 3, 4, 5. the second column is labeled distance (feet) with entries 530; 1,050; 1,600; 2,110; 2,650. which type of model best describes the relationship? linear, because the r value for the linear model is closest to 1 exponential, because the r value for the exponential model is closest to 0 linear, because the rate of change between each pair of points is exactly 520 exponential, because the rate of change between each pair of points is 1.98
  
• at the corner store, nico bought 5 pencils for $0.10 each and 3 pens for $0.50 each. he used t to represent the sales tax, in dollars, that he also paid. he paid a total of $2.12, including tax. nico wrote this equation to represent what he paid. what errors, if any, did he make? 5(0.10) + 3(0.50) - t = 2.12 he should have multiplied 0.10 by 3 instead of 5. he should have multiplied 0.50 by 5 instead of 3. he should have added t instead of subtracting t. he should have multiplied by t instead of subtracting t.
