Answer:
Carmen received $7.14 for each hour she worked.
Step-by-step explanation:
$350 for 49 hours of work
Write an equation, with hours as the variable
$350 = 49h

h = $7.14
Carmen received $7.14 for each hour she worked.

Answer: Vertically

The ratio is 9 : 7 which means for every 9 pounds of Quartz you have 7 pounds Marble. For the second row Quartz is 72. For the third row it's 11 bags because 99/9 = 11 and 11 times 7 equals 77. The four one is 126 pounds Quartz. Finally the last one is 15 bags and 15 times 7 is 75 pounds of Marble. What you do with the ratio is multiply by the number of bags to figure out with this many bags how many Quartz or Marble. You can do the same thing to figure out how many bags.
