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?

Respuesta :

Answer:

[tex]Total = \$73[/tex]

Step-by-step explanation:

Given

[tex]Three\ 8lb = \$2.25/lb[/tex] --- Dog Food

[tex]Two\ 4lb = \$1.75/lb[/tex] ----- Cat Food

[tex]Three\ \frac{1}{4}lb = \$6.98[/tex] -------- Fish Food

Required

Determine the amount spent

For Dog Food

[tex]1\ lb = \$2.25[/tex]

Amber bought 8lb.

So, that is:

[tex]8 * 1\ lb = \$2.25 * 8[/tex]

[tex]8\ lb = \$18[/tex]

He bought 3 of those;

[tex]Cost = 3 * \$18[/tex]

[tex]Cost = \$54[/tex]

For Cat Food

[tex]1\ lb = \$1.75[/tex]

Amber bought 4lb

So, that is:

[tex]4 * 1\ lb = 4 * \$1.75[/tex]

[tex]4\ lb = \$7[/tex]

He bought 2 of those;

[tex]Cost =2 * \$7[/tex]

[tex]Cost =\$14[/tex]

For Fish Food

[tex]1\ lb = \$6.98[/tex]

Amber bought 1/4lb

So, that is:

[tex]\frac{1}{4} * 1\ lb = \$6.98 * \frac{1}{4}[/tex]

[tex]\frac{1}{4}\ lb = \$1.745[/tex]

He bought 3 of those;

[tex]Cost = 3 * \$1.745[/tex]

[tex]Cost = \$5.235[/tex]

Total amount spent  is:

[tex]Total = \$54 + \$14 + \$5.235[/tex]

[tex]Total = \$73.235[/tex]

[tex]Total = \$73[/tex] (approximated)
