A local store is selling 6 bottles of glue for $3.78. which scale factor could be used to calculate the cost of 42 bottles of glue?

Respuesta :

$26.46, because for 6 bottles it costs $3.78, so then you have to find what one bottle costs which is 0.63¢ then you multipy that buy 42 because thats how many bottles of glue you need!:)
