Answer:

C. 24

Step-by-step explanation:

by algebra:

let "?" be x

35/30 = 28 / x (multiply both sides by 30)

35 = (28/x) (30) (multiply both sides by x)

35x = (28)(30)

35x = 840 (divide both sides by 35)

x = 840 / 35

x = 24

Erika worked 14 hours last week and 20 hours this week. If she earns $9 per hour, how much did she earn during these two weeks

IrinaK [193]

$9 per hour for 14 hours the first week can be found by doing 9 • 14, which equals 126.
In the first week, Erika earned $126.
$9 per hour for 20 hours for the second week can be found by doing 9 • 20, which equals 180.
In the second week, Erika earned $180.
To find the total amount Erika earned in both weeks, add how much she made in week 1 to how much she made in week 2.
126 + 180 = 306
Erika made $306 during these 2 weeks.
