Answer:
Formula for the cost c, in pence, of ordering x prints
C = 12x + 60p
a) 204p
b) 348p
Step-by-step explanation:
A website offering digital photo printing charges 12p per print plus 60p postage.
Write down a formula for the cost c, in pence, of ordering x prints
Hence: formula for the cost c, in pence, of ordering x prints
C = 12x + 60p
Where x = number of prints
a) For 12prints
C = 12 × 12 + 60p
C = 204p
b) 24prints.
C = 12 × 24 + 60p
C = 348p
Express incrase as percent of original
incrase=new-original=680-500=180
percent increase=increase/original times 100=180/500 times 100=0.36 times 100=36
36% increase
