Answer:
I think it would be 120
Step-by-step explanation:
You add 120+120 and it would equal 240. Then 240 dived by 2 which will equal 120.
(120 + 120)= 240 dived by 2= 120 I might be wrong
There is no picture of a receipt to see.
but do the cost of food times 0.15 to find out the tip. then do the cost of the food times 1.0875 to find out how much the total would be. then add the tip to the total.

Answer:
She earned $959.2 last week.
Step-by-step explanation:
This question can be solved using a rule of three.
Base:
$500.
On commissions:
She earns 8.2% on commissions.
She sold $5,600, which is 100% = 1. How much is 8.2% = 0.082?
x - 0.082
5600 - 1
x = 5600*0.082 = 459.2.
She earns $459.2 on commissions.
Total:
500 + 459.2 = $959.2
She earned $959.2 last week.
Answer
Let t be number of minutes since tap is opened
water is increased by 20 gallons of water per minute.
sugar increase rate of 3 pounds per minute
water :- W(t) = 350 + 10 t
sugar :- S(t) = 10 + 3 t
concentration
C(t) = 
at t = 15 minutes
C(15) = 
C(15) = 
C(15) = 0.11
at beginning t = 0 minutes
C(0) = 
C(0) = 
C(0) = 0.0286
C(15) > C(0)
hence, concentration is increasing as time is passing.
There are 20 cassettes.
Step-by-step explanation:
Given,
Ratio of cassette to compact disc = 10:3
Let,
the number of cassettes = 10x
Number of compact disc = 3x
According to given statement;
the number of cassettes is 10 less than 5 times the number of compact discs.
10x = 5(Number of CD) - 10

Dividing both sides by 5

Number of cassettes= 10x = 10(2) = 20
There are 20 cassettes.
