5(20) + 4y = 216
100 + 4y = 216
4y = 216 - 100
4y = 116
y = 116/4
y = 29so they sold 29 four-dollar yogurts + 20 five-dollar yogurtsfor a total of 49 yogurts sold <==

x= 2597/335

Step-by-step explanation:

2.4x-9.1x= -6.7x

-39.44-12.5 = -51.94

-6.7x=-51.94

divide both sides by -6.7

x= 2597/335
