Answer:
The inequality that can be used to determine the number of guitar lessons Gale could take using her birthday money is:
The solution to the inequality is:
She can take at most, 6 guitar lessons
Step-by-step explanation:
Total amount Gale received is $200
For rental equipment, she paid $50
Each guitar lesson will cost $25
Let x represent the number of lessons she could take, then the total amount she will spend must bot exceed $200
The guitar lesson will cost a total of 25x
So, her total spending will be:
This must be at most $200
Solving the above inequality:
x+y =27 sum of two numbers is 27
x=y+3 One of the numbers is three more than the other
substitute x=y+3 into the first equation
(y+3) + y = 27
combine like terms
2y + 3 = 27
subtract 3 from each side
2y = 24
divide by 2
y =12
x = y+3
x = 12+3
x =15
the two numbers are 12 and 15
Well when there is a minus sign and a parenthesis and another minus sign after it it makes a plus sign so all you have to do is 2+5 and the answer is 7
