What you have to note about solving inequality equations like this:
- When you divide by a minus, you flip the sign in the inequality.
- When there's an absolute value symbol, because whatever is inside could be positive or negative, you have to find values for each case like I've done.
Q1)
write the equation that estimates the number of trinkets T that will be in the storeroom after H hours
Initially the number of trinkets available = 560
every hour they sell an average of 5 trinkets
therefore in H hours, number of trinkets that will be sold = 5 trinkets/hr * H hrs
number of trinkets sold in H hours = 5H
the remaining number of trinkets = T
T = number of trinkets initially available - number of trinkets sold
T = 560 -5H
Q2)
How many days will it take to run out of trinkets
number of trinkets sold per hour - 5
number of hours the shop is open for - 14 hours / day
during one day number of trinkets sold - 5 trinkets/hr x 14 hrs/ day
= 70 trinkets per day
there are 560 trinkets available
and if 70 trinkets are sold per day
number of days it takes to sell 560 trinkets
days = 560 trinkets / 70 trinkets/day
= 8 days
the third response is correct - 1) T = 560 -5H
2) 8 days
