Let x = hours worked as a clerk ($12 per hour).Let y = hours worked as a cashier ($8.25 per hour).She worked 55 hours, thereforex + y = 55 (1)She earned $585, therefore12x + 8.25y = 585 (2)From (1), obtainy = 55 - x (3)Substitute (3) into (2).12x + 8.25(55 - x) = 58512x + 453.75 - 8.25x = 5853.75x = 131.25x = 35y = 55 - x = 55 - 35 = 20
Answer: c) Office clerk: 35 hours; cashier: 20 hours.

Answer:
110 is answer.
Step-by-step explanation:
Given that first term is 185
Each term is got by subtracting 15 from the previous term
Hence we have an arithmetic sequence with a = 185 and d = common difference =-15
6th term would be
a_6 = a+(6-1)d = 185+5(-15)
=110
Verify:
185, 170, 155,140,125,110
We get by subtracting 15 the same answer as the 6th term
Answer:
Step-by-step explanation:
Simple Interest formula S.I = Principal * rate * time
S.I = P * r *t
In this case Simple interest ; S.I = $4.56
Principal; P = $19.00
rate; r = 4% or 0.04 as a decimal
t = total duration of investment in years.
Next, plug in the numbers in the S.I formula and solve for <em>t</em>
4.56 = 19 * 0.04 * t
4.56 = 0.76t
Divide both sides by 0.76;
4.56 / 0.76 = t
t = 6
Therefore, it will take 6 years to earn a simple interest of $4.56
