When karen serves jury duty, she will receive $15 each day for the first three days she serve. After three days, she will receiv

liubo4ka [24]

Karen received $ 213 for 10 days of serving

<em><u>Solution:</u></em>

Given that When karen serves jury duty, she will receive $15 each day for the first three days she serve

To find: money received by karen if she served for 10 days

First three days = $ 15 each day

Therefore,

first day = $ 15

second day = $ 15

third day = $ 15

After three days, she will receive $24 each day she serves

4th , 5th, 6th, 7th , 8th , 9th, 10th day = $ 24 each day

If she serves for 10 days,

money received = 15 + 15 + 15 + 24 + 24 + 24 + 24 + 24 + 24 + 24

money received = 3(15) + 7(24)

money received = 45 + 168 = 213

Thus karen received $ 213 for 10 days of serving
