$2.76/18 • $2.07/x cross multiply these proportions $2.76•x = $2.76x. $2.07•18= $37.26 then divide by 2.76 on both sides $2.76/$2.76 that cancels out and you get x $37.26/$2.76= 13.5 so that means x= 13.5 your answer is 13.5
apologiabiology
amount/price=18/2.76
18/2.76=x/2.07
times both sides by 2.76*2.07 aka cross multiply
18*2.07=2.76x
37.26=2.76x
divide both sides by 2.76
13.5=x

costs $13.5
