Question

Amber bought three 8 pound bags of dog food at $2.25 per pound, two 4 pound bags of cat food at $1.75 per pound, and three 1/4 pound bags of fish food at $6.98 per pound. Approximately how much did Amber spend on pet food?

Answer 1

Answer:

$Total = \ 73$

Step-by-step explanation:

Given

$Three\ 8lb = \ 2.25/lb$ --- Dog Food

$Two\ 4lb = \ 1.75/lb$ ----- Cat Food

$Three\ \frac{1}{4}lb = \ 6.98$ -------- Fish Food

Required

Determine the amount spent

For Dog Food

$1\ lb = \ 2.25$

Amber bought 8lb.

So, that is:

$8 * 1\ lb = \ 2.25 * 8$

$8\ lb = \ 18$

He bought 3 of those;

$Cost = 3 * \ 18$

$Cost = \ 54$

For Cat Food

$1\ lb = \ 1.75$

Amber bought 4lb

So, that is:

$4 * 1\ lb = 4 * \ 1.75$

$4\ lb = \ 7$

He bought 2 of those;

$Cost =2 * \ 7$

$Cost =\ 14$

For Fish Food

$1\ lb = \ 6.98$

Amber bought 1/4lb

So, that is:

$\frac{1}{4} * 1\ lb = \ 6.98 * \frac{1}{4}$

$\frac{1}{4}\ lb = \ 1.745$

He bought 3 of those;

$Cost = 3 * \ 1.745$

$Cost = \ 5.235$

Total amount spent  is:

$Total = \ 54 + \ 14 + \ 5.235$

$Total = \ 73.235$

$Total = \ 73$ (approximated)
