Answer :
Answer:
He saved $25.
Step-by-step explanation:
- If Rob saves $5 for every $16 he earns, he is saving the folowing franction of his income: [tex]\frac{5}{16} =0,3125=31,25\%[/tex].
- Then if his income equals $16, he will save [tex]\$16\times{0,3125}=\$5[/tex].
- If his income is $80, he will save [tex]\$80\times{0,3125}=\$25[/tex]
- Another way to understand this problem would be to think that [tex]\$80=5\times{\$16}[/tex]. Then, receiving $80 is the same as receiving 5 times $16. If he saves $5 for every $16 he receives, he would save 5 times $5 = $25.
