Here are the step-by-step solutions for each problem on the worksheet.
1. Peter's Shopping
*
Step 1: Identify the items bought: 19 cupcakes, 18 small pies, and 47 loaves of bread.
*
Step 2: Add them all together to find the total: $19 + 18 + 47$.
* First, add $19 + 18 = 37$.
* Then, add $37 + 47 = 84$.
*
Result: Peter bought 84 items altogether.
2. Sandra's Earnings
*
Step 1: Identify the money earned each day: $\$92$, $\$83$, $\$44$, and $\$107$. (Friday is off, so it counts as $\$0$).
*
Step 2: Add the amounts together: $92 + 83 + 44 + 107$.
* $92 + 83 = 175$
* $175 + 44 = 219$
* $219 + 107 = 326$
*
Result: Sandra earned $\$326$ that week.
3. Simon's Flights
*
Step 1: Identify the length of each flight: 7.5 hours, 5.5 hours, and 8 hours.
*
Step 2: Add the times together: $7.5 + 5.5 + 8$.
* First, add the decimals: $7.5 + 5.5 = 13$ hours.
* Then, add the last flight: $13 + 8 = 21$ hours.
*
Result: Simon was flying for 21 hours.
