Step-by-step explanation:
what the answer is?
Frank worked 25 hours as a waiter last week.
<h2>Simultaneous equation</h2>
- Let the time spent as a waiter be x
- Leet the total time spent as a busser be y
If<u> Frank worked both jobs f</u>or a total of 36 hours, hence:
x + y = 36
x = 36 - y
Also, if he earns $12 per hour as a waiter and $10 per hour as a busser and earned a total of $410, then;
12x + 10y = 410
Substitute 1 into 2
12x + 10y = 410
12(36 - y)+ 10y = 410
432 -12y + 10y = 410
-2y = -22
y = 11
Since x = 36 - y
x = 36 - 11
x = 25
Hence frank worked 25 hours as a waiter last week.
