Answer:

<em>90 calories in total</em>

Step-by-step explanation:

<em>We can solve this equation through the following steps:</em>

<em>Step One: Since we are told that a banana is 20 less calories than an orange, we can create the Let Statements:</em>

<em>Let x= the calories in a banana</em>

<em>Let x-20=the calories in an orange</em>

<em>Step Two: Create an equation</em>

<em>Since we are told "7 bananas have the same calories as 9 oranges" we translate"</em>

<em>7x=9(x-20) Distribute</em>

<em>7x=9x-180 Subtract 9x from both sides of the equation</em>

<em>7x-9x=-180 Simplify</em>

<em>-2x=180 Divide both sides by -2</em>

<em>x=90</em>

<em>∴There are 90 calories in a banana. </em>
