Answer:

It will take Chris 13 weeks of allowance to save enough to buy the computer.

Step-by-step explanation:

Chris needs $858 to buy a computer.

She has already saved $575.

She gets $15 an hour for babysitting and will babysit 12 hours in the next month, then she will get for babysitting:

($15/hour)(12 hours)=$180

Then, Chris will need:

A=$858-$575-$180→A=$103

She can save &8 a week form her allowance, then she will need:

Number of weeks: n = $103 / ($8/week) → n=12.875 weeks

Rounding:

n=13 weeks

snow_tiger [21]

Answer:

  -12.5%

Step-by-step explanation:

A percentage change is computed using ...

  percent change = ((new amount) -(original amount))/(original amount) × 100%

We want to find the percentage change from 4.8 m, so we have ...

  percent change = (4.2 -4.8)/4.8 × 100% = -.6/4.8×100% = -12.5%

The carpenter made the track 12.5% too short.
