$85.20/6= $14.20/pair is the answer because unit price equals cost/pairs
32 + 0.33c = p
where c is every card more than 80 (so if you want 82 card c = 2)
and p is the total price
Answer:
4
Step-by-step explanation:
the absolute value of -7 is seven and the absolute value of 3 is 3.
7-3=4
Answer:
16 years
Step-by-step explanation:
Let x represent the number of years. The suburb population is growing at a rate of 5000 per year after x years, it can be represented by the equation:
320000 + 5000x
The city population is declining at a rate of 14000 per year after x years, it can be represented by the equation:
624000 - 14000x
The number of years for the city and suburb population to be equal can be gotten from:
320000 + 5000x = 624000 - 14000x
14000x + 5000x = 624000 - 320000
19000x = 304000
x = 304000 / 19000
x = 16
In 16 years the populations of the suburb and the city be equal
