If 2/3 kilo of beef costs 160 pesos, then how much will 3 kilos of beef cost?

Sagot :

let 'p' be the cost per kilo
-----------------
2/3p = 160
p = 160(3)÷2
p = 240
----------------
for 3 kgs.
3 kgs × 240/kgs = 720
-----------------
3 kilos costs 720.
[tex]Let\ x\ be\ the\ cost\ of\ beef\ per\ kilo. \\ \\ Solution; \\ \frac{2}{3}x=160 \\ \\ (3) \frac{2}{3}x=160(3) \\ \\ 2x=480 \\ \\ \frac{2x}{2}=\frac{480}{2} \\ \\ \boxed{x=240} \\ \\ Solve\ for\ the\ problem\ where\ x=240 \\ \\ 3x\to3(240)\to\boxed{\boxed{720}} \\ \\ Therefore,\underline{Php\ 720}\ is\ the\ cost\ of\ 3\ kilos. \\ \\ Hope\ it\ Helps:) \\ Domini [/tex]
