Answer 1

Kay and Jerry have a yearly household budget for food and clothing that must not exceed $5200

Thus, we must have that

`\begin{gathered} \text{ the sum of the food cost and the clothing cost for the year must be less than or} \\ \text{ \$5200} \end{gathered}`

This means that

`x+y\le5200`

Their food cost includes going out to dinner one night each weekend, or 52 times a year, and spending an average of $20 or less. Food cost also includes $70 or less per week for groceries.

Hence,

`\begin{gathered} x\le(52*20)+(52*70) \\ \text{ thus} \\ x\le1040+3640 \\ x\le4680 \end{gathered}`

Hence, the system of inequalities that represents their budget is given by

x ≤ 4680, x + y ≤ 5200
