Is there a formula to figure out og based on blending known amounts and gravities of 2 worts?

I had a 3 1/4 gal batch of 1.038 and blended in 2 gals of 1.088. What would my blended og be?

The smaller gravity batch already had yeast pitched the day before, so I couldn't simply mix and measure. Thanks!

I did some calculations adding gravity points then multiplying by volume. Added both numbers together then divided by total volume to get 1.057. Is this correct?
