Answer

$2023$

Work Step by Step

Substituting $y=700$ in the given equation, $ y=13.34x+5.36 ,$ results to \begin{array}{l}\require{cancel} 700=13.34x+5.36 \\ 700-5.36=13.34x \\ 694.64=13.34x \\ \dfrac{694.64}{13.34}=x \\ x=52.071964017991004497751124437781 .\end{array} Rounded up, then $x=53.$ Hence, the restaurant sales will exceed $\$700$ billion $53$ years after $1970$ or in the year $ 2023 .$
