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)
