Answer:
After 5 hours the two would charge the same amount of money.
Step-by-step explanation:
Designer A: $450 + ($105/hr)x, where x is the number of hours worked;
Designer B: $725 + ($50/hr)x
Equating these two formulas, we get:
$450 + ($105/hr)x = $725 + ($50/hr)x
Subtracting $450 from both sides: ($55/hr)x = $275
Dividing both sides by $55 yields the number of hours worked:
x = $275/$55 = 5
After 5 hours the two would charge the same amount of money.
Answer:
5 hours
Step-by-step explanation:
The cost for designer A
450+105h
The cost for designer B
725+50h
We want to know when the cost is the same
Set the expressions equal
450+105h =725+50h
Subtract 50h from each side
450+105h-50h =725+50h-50h
450+55h = 725
Subtract 450 from each side
450+55h-450 = 725 -450
55h = 275
Divide each side by 55
55h/55 =275/55
h =5
At 5 hours the cost is the same
