In the first 4 hours it is open, the deli sells 23 hams. the deli expects to sell h more hams before the end of the day. write two expressions that model the number of hams sold that day.

Assuming they're expecting to sell at the same rate:

first we divide the number of hams sold by the time it took to sell them

23/4=5.75

this is is the rate per hour at which the hams are being sold

y=23+h
h=5.75*x

in these two equations, y=the total number of hams sold and x= the number of hours the store is open after the first 4 hours
