Q. 3.5c1.5d50 3.5 c-1.5 d \geq 50 \newlineEsa's Pastries sells cupcakes for $3.50 \$ 3.50 each and donuts for $1.50 \$ 1.50 each. The given inequality represents the difference, in dollars, between cupcake sales and donut sales on a typical day based on c c , the number of cupcakes sold and d d , the number of donuts sold. If Esa sold 200200 donuts on a typical day, what is the minimum number of cupcakes she sold on that day?\newlineChoose 11 answer:\newline(A) 2525\newline(B) 5050\newline(C) 100100\newline(D) 350350
  1. Substitute Value of dd: Substitute the value of dd into the inequality.\newlineGiven the inequality 3.5c1.5d503.5c - 1.5d \geq 50 and knowing that Esa sold 200200 donuts, we substitute dd with 200200.\newline3.5c1.5(200)503.5c - 1.5(200) \geq 50
  2. Perform Multiplication: Perform the multiplication.\newlineCalculate 1.5×2001.5 \times 200 to find the total sales from donuts.\newline3.5c300503.5c - 300 \geq 50
  3. Isolate Term with c: Isolate the term with c.\newlineAdd 300300 to both sides of the inequality to isolate the term with c.\newline3.5c300+30050+3003.5c - 300 + 300 \geq 50 + 300\newline3.5c3503.5c \geq 350
  4. Solve for c: Solve for c.\newlineDivide both sides of the inequality by 3.53.5 to find the minimum number of cupcakes cc.\newlinec3503.5c \geq \frac{350}{3.5}
  5. Perform Division: Perform the division.\newlineCalculate 350350 divided by 3.53.5 to find the minimum number of cupcakes.\newlinec100c \geq 100
