carpet to cover a floor area 15m2 costs £110. how much would you expect to pay for a similar carpet measuring 5m by 4.2m?

£ 153.93 = £154  

Step-by-step explanation:

area 1 = 15 m^2

cost= £110

cost per meter =£7.33 m^2

area= 1 x b= 5 x 4.2= 21 m^2

Cost = 21 x £7.33=£ 153.93 ~ £154  

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..
