Answer:
She will have 19 ¹/₂ batches of purple paint
Step-by-step explanation:
<em>r </em>+<em> b </em>= 1<em> bp</em>
³/₄ <em>r</em> + ³/₄ <em>b </em>= 1<em> bp</em>
(³/₄ + ³/₄) * 13 = <em>x bp</em>
⁶/₄ = 1 ¹/₂
1 ¹/₂ * 13 = 13 ¹³/₂ = 19 ¹/₂ batches
VARIABLE KEY:
<em>r</em> = red
<em>b</em> = blue
<em>bp</em> = batches of purple
<em>x</em> = total number of <em>bp</em>
Good luck!!
She will have 19.5 cups of purple paint.
