Answer:
<span>$37.08</span>
Explanation:
1 dozen = 12 pieces
so 4 dozens = <span>4⋅12=48</span> bagels
let x = cost of 48 bagels
by ratio and proportion
<span><span><span>$2.99</span>6</span>=<span>x48</span></span>
Multiply both sides by 48 to isolate x.
<span><span><span>$2.99<span>(48)</span></span>6</span>=x</span>
<span><span><span>$143.52</span>6</span>=x</span>
<span>$23.92=x</span>
Note: You can also factor 48 into <span>6⋅8</span> and cancel common factor 6
to get <span>$2.99<span>(8)</span>=$23.92</span>
Let y = cost of 16 muffins
by ratio and proportion
<span><span><span>$3.29</span>4</span>=<span>y16</span></span>
Multiply both sides by 16 to isolate y.
<span><span><span>$3.29<span>(16)</span></span>4</span>=y</span>
<span><span><span>$52.64</span>4</span>=y</span>
<span>$13.16=y</span>
Note: You can also factor 16 into <span>4⋅4</span> and cancel common factor 4
to get <span>$3.29<span>(4)</span>=$13.16</span>
Add the cost of 4 dozen bagels and 16 muffins.
<span>$23.92+$13.16=$<span>37.08</span></span>
