Question

If a store sells paintbrush at $\$1.50$ each and canvases at $6$ times the price of paintbrush, then the total cost for $p$ paintbrushes and $c$ canvases, (in dollars), is

• A. $7.5pc$
• B. $10.5pc$
• C. $9c+1.5p$
• D. $10.5(p+c)$

Answer 1

The correct option is C $9c+1.5p$

Given cost of paintbrush is $1.50 and cost of canvases is 6 times the cost of paint brush

Then cost of canvases=$6\times 1.5=9$ is $9

So cost of p paint brush =1.5p

And cost of c canvases =9c

Then total cost of p paint brush and c canvases =9c+1.5p
