Mark worked 7.5 hours last Saturday at his part-time job. if make earns $7.80 per hour, how much did he earn on Saturday?

not enough to support Mark's growing family.

Step-by-step explanation:

if minimum wage is about 8 dollars, and is only enough to support one person comfortably, then the hourly wage of 7.80 would not be enough to support his twin girls, their older brother, and Mark's new baby. especially if he only works 7.5 hour shifts. lets say mark works five days a week; monday, tuesday,  thursday, friday, and saturday. if he works 7.5 hours a day, at 7.80 an hour, that is approximately 292.50 dollars a week. and if he works that for a whole year, he will only be making 15,210 dollars a year, which is way under the 68,703 average yearly wage in the US.
