Each week Charlene uses 3/4 of a bag of cat food to feed her cats. She has 112 bags of cat food in stock. How long will her stoc
inessss [21]

The stock of cat food will last for 149 weeks.

Step-by-step explanation:

Given,

Bags of cat food in stock = 112

Bags used each week = \frac{3}{4}\ of\ one\ bag

Let,

x be the number of weeks.

Therefore,

\frac{3}{4}x=112

Multiplying both sides by 4/3

\frac{4}{3}*\frac{3}{4}x=112*\frac{4}{3}\\x=\frac{448}{3}\\x=149.33

Rounding off to nearest whole number;

x=149

The stock of cat food will last for 149 weeks.
