Jack has a summer job caddying at a golf course. Jack earns $120
a week. By rounding his weekly income to the nearest hundred
dollars, find a reasonable estimate for his total income during the
12 week summer.
OA) $700
O B) $800
OC) $1200
OD) $1700

His total income during the summer is $1200 ⇒ C

Step-by-step explanation:

To round a number to a nearest given digit

Examples:

1. Round 1235 to the nearest hundred, the hundred digit is 2 and the digit right to it is 3, then keep the hundred digit 2 and put all the digit right to it 0, so the answer is 1200

2. Round 1265 to the nearest hundred, the hundred digit is 2 and the digit right to it is 6, then add the hundred digit 2 by 1 and put all the digit right to it 0, so the answer is 1300

Now let us solve the problem

∵ Jack earns $120  a week

- By rounding his weekly income to the nearest hundred  dollars

∵ The hundred digit is 1

∵ The digit right to it is 2

- Keep the hundred digit 1 and put the digits right to it 0

∴ The rounded number is 100

∴ Jack earns $100 per week

- To estimate his total income during the  12 week summer

   multiply 100 by 12

∴ His total income during the summer = 100 × 12

∴ His total income during the summer = $1200

chase is right because he already been to the swings and he know how far it will be to get there
