Answer:
The correct options are;
1) Continue walking 5 dogs per week, but increase his rate to $5 per dog
4) Double the amount of dogs walked per week but keep the same rate of $3 per dog
Step-by-step explanation:
The parameters given are;
Jonah is hoping to earn $200 from 8 weeks of dog walking
Therefore, Jonah has to make $200/8 per week or $25 per week
1) Continue walking 5 dogs per week, but increase his rate to $5 per dog
With the above strategy, Jonah will make $5 × 5 = $25 per week which will amount to $25 × 8 = $200 in 8 weeks total
2) Walking 5 dogs per week at $4 per dog = $20 per week and 8 × $20 = $160 in 8 weeks
3) Walking 8 dogs per week at $3 per dog = $24 per week and 8×$24 = $192 in 8 weeks
4) Double the amount of dogs walked per week to 5×2 or 10 dogs per week but keep the same rate of $3 per dog would give him 10 × $3 = $30 per week and 8 × $30 = $240 in 8 weeks
5) Double the amount of dogs walked per week to 5×2 or 10 dogs per week and cut his rate to $2 per dog would give him 10 × $2 = $20 per week and 8 × $20 = $160 in 8 weeks
Therefore, the strategies that would allow Jonah to reach his $200 goal in 8 weeks are;
1) Continue walking 5 dogs per week, but increase his rate to $5 per dog
4) Double the amount of dogs walked per week but keep the same rate of $3 per dog.
