Here are the step-by-step solutions for each problem. Remember, the instructions say to round your final answer to the nearest dollar.
1) Julia bought 49 flowers for $1.50 each. Find the total cost of buying the flowers?
*
Step 1: Multiply the number of flowers by the cost per flower.
$$49 \times \$1.50 = \$73.50$$
*
Step 2: Round to the nearest dollar.
Since the cents are .50, we round up to the next whole dollar.
$$\$73.50 \rightarrow \$74$$
2) A trip to New York costs $66.75 per person. If there is a group of 11 travellers visiting the city, find the total cost incurred by them.
*
Step 1: Multiply the cost per person by the number of people.
$$11 \times \$66.75 = \$734.25$$
*
Step 2: Round to the nearest dollar.
Since the cents are .25 (which is less than .50), we keep the dollar amount the same.
$$\$734.25 \rightarrow \$734$$
3) Clara bought a cake for $25, 50 cupcakes for $0.75 each and 50 cookies for $0.50 each for her birthday party. How much did she spent in total?
*
Step 1: Calculate the cost of the cupcakes.
$$50 \times \$0.75 = \$37.50$$
*
Step 2: Calculate the cost of the cookies.
$$50 \times \$0.50 = \$25.00$$
*
Step 3: Add the cost of the cake, cupcakes, and cookies together.
$$\$25.00 \text{ (cake)} + \$37.50 \text{ (cupcakes)} + \$25.00 \text{ (cookies)} = \$87.50$$
*
Step 4: Round to the nearest dollar.
Since the cents are .50, we round up.
$$\$87.50 \rightarrow \$88$$
4) Rob saves $2.25 from his pocket money everyday. How much does he save in 1 month?
*
Step 1: Determine the number of days in a month. In math problems like this, unless a specific month is named, we usually assume a standard month has 30 days.
*
Step 2: Multiply the daily savings by the number of days.
$$30 \times \$2.25 = \$67.50$$
*
Step 3: Round to the nearest dollar.
Since the cents are .50, we round up.
$$\$67.50 \rightarrow \$68$$
