Answer: the number is 3
Step-by-step explanation:
Let the number be represented by x.
If 4 more than 4 times a certain number is the same as 4 more than the product of 3 and 4, it means that
4x + 4 = 4 + 3×4
4x + 4 = 4 + 12
4x + 4 = 16
Subtracting 4 from the left hand side and the right hand side of the equation, it becomes
4x + 4 - 4 = 16 - 4
4x = 12
Dividing the left hand side and the right hand side of the equation by 4, it becomes
x = 12/4 = 3
Answer:
a.) After using the coupon the total comes out to 32.75
b.) It shows a different way buy adding 10 with the number of hours times the price per hour minus the discount.
Step-by-step explanation:
Expression A: 18x dollars (Before coupon)
Expression B: 18x dollars (Before coupon)
To use the coupon, subtract 1.5 with 8 giving you 7.5 per hour replacing the 8's with 7.5
For example: [A] (10+7.5h)
220c-287=103
add 287 to both sides
220c=390
divide both sides by 220
c=1.77
B. h=3/4 ( I Just worked this out)
