Yes because there is 1 whole 3/4, 1/2, 1/4
Also 1/4 is 1/2 of 1/2 lol I luv math
The question seems to be pointing towards a multiple choice response but I will do my best. The first equation would be 15x+12y=9.30 and the second would be 10x+4y=4.60, x represents flour and y represents sugar.
Hope this helps.
