Question

30 POINTS I WILL GIVE BRAINLIEST! Please write an equation using the criteria above and explain how to solve it. THANK YOU!!!

Answer 1

Example values:

The waiter will earn 5 dollars per hour. He worked for 7 hours last night. He made 50 dollars in tips.

An equation can be made with these variables:

$ab + c = d$

$a = 5, b = 7, c = 50$
$5(7) + 50 = d$
$35 + 50 = 85$

$d = 85$

The waiter would make 85 dollars that evening.

Answer 2

A = dollars per hour
b = hours
c = tips
d = total amount

Let's say, for example, that the waiter makes $7.25 per hour (today's minimum wage). 

a = $7.25

The average hours worked per day is 7 hours.

b = 7

tips will remain as a variable

c = t

dollars made at the end will also be a variable (as you do not know the tip)

d = d

So you're equation will look like: 

7.25(7) + t = dNote that 7.25(7) = 50.75tips   | total----------------$1        |   $51.75$1.50   |   $52.25$2       |   $52.75
-----------------------------------------------------------------------------------------------------a = dollars per hour
b = hours
c = tips
d = total amount

Another variable you can make (if you do not follow the 7 hour work day), is the amount of hours worked each day

Let us say that the waiter still makes $7.25
a = $7.25

hours (b) = h

tips (c) = $2.00

total amount (d) = d

You're equation will be: 7.25(h) + 2 = d

   h   |    d
--------------
   1   | $9.25
   2   | $16.50
   3   | $21.75
