Ответ:
x=12Cost of one package of sugar cookie dough =$12
y=16Cost of chocolate chip cookie dough=$16
Step-by-step explanation:
The question is on formation of simultaneous equations
Let Sugar cookie dough to be x
Let chocolate chip cookie dough to be y
Equations
Lisa13x + 6y = $252(a)
Julia8x + 12 y= $288(b)
Solving the equations
12(13x + 6y = 252)156x +72y=3024
6(8x + 12 y= 288)48x + 72y=1728
Eliminate 72y by subtraction
108x=1296divide both sides by 108 to remain with x
x=1296/108x=12(c)
substitute (c) in (a) above
13x + 6y = 252
(13×12)+ 6y =252
156+6y=252
6y=252-156
6y=96divide both sides by 6 to remain with y
y=96/6 =16
Solutions
x=12Cost of one package of sugar cookie dough =$12
y=16Cost of chocolate chip cookie dough=$16
