Marcus earned $230 for 40 hours of work. Phillip earned $192 for 32 hours of work. Are these pay rates proportional? Explain.

No.

Step-by-step explanation:

Find ROC for Marcus and Phillip

Marcus

230/40 = $5.75 per hour

Phillip

192/32 = $6 per hour

$6 > $5.75

These pay rates are not proportional

Step-by-step explanation:

Dividing 230 by 40 gave 5.75, so Marcus earns $5.75 per hour he works

However, dividing 192 by 32 gives 6, which shows that Phillip earns $6 per hour and $0.25 more than Marcus

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
