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

`Total = \$73`

Explanation:

Given

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

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

`Three\ (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:

`(1)/(4) * 1\ lb = \$6.98 * (1)/(4)`

`(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)
