Question

scott and his stepdad like to build models together. the bar graph shows how many models of each type they have built so far. models built so far if scott and his stepdad spent an average of $15 on each model, how much money have they spent on models so far? $ submit work it out not feeling ready yet? this can help:

Explanation:

Step1: Calculate total number of models

From the bar - graph, number of boat models \(=3\), car models \(=6\), airplane models \(=3\), building models \(=5\).
Total number of models \(=3 + 6+3 + 5\)

$$=17$$

Step2: Calculate total money spent

Average money spent per model \(=\$15\).
Total money spent \(=\text{Average per model}\times\text{Total number of models}\)

$$=15\times17$$

$$ = 255$$

Answer:

\(255\)
