The trinket store is open for 14 hours per day. They sell an average of 5 trinkets per hour. The back storeroom currently has 560 trinkets in it

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
