Question

Rob is saving to buy a new MP3 player for every $16 he earns babysitting he saved $5 on Saturday rob earned $80 babysitting how much money did he save

Answer 1

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: $\frac{5}{16} =0,3125=31,25\%$.
• Then if his income equals $16, he will save $\ 16\times{0,3125}=\ 5$.
• If his income is $80, he will save $\ 80\times{0,3125}=\ 25$
• Another way to understand this problem would be to think that $\ 80=5\times{\ 16}$. 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.
