Q. QuEsnow

5

of

10

: Your price for Chicken Parmesan is

\mathbf{\$ 1 1 . 9 9 .}

Your food cost for this item is

\$ 4.31

. You change you menu prices to be

30 \%

ef thout east. By what percentage will the price of Chicken Parmesan increase?

\newline

a)

15 \%

\newline

b)

17 \mathrm{~s}

\newline

c)

20 \%

\newline

d)

2376

Calculate Increase: First, calculate the new price after a $30$ % increase. The increase is $30$ % of the original price, which is $\$11.99$ . $\newline$ Increase = $30$ % of $\$11.99$ = $0.30 \times \$11.99$
Find New Price: Now, add the increase to the original price to find the new price. $\newline$ New Price = Original Price + Increase = $\$11.99$ + $0.30 \times \$11.99$
Round to Nearest Cent: Perform the calculation to find the new price. $\newline$ New Price = $\$11.99 + \$3.597 = \$15.587$ $\newline$ Since prices don't usually include fractions of a cent, we'll round to the nearest cent. $\newline$ New Price = $\$15.59$
Calculate Percentage Increase: To find the percentage increase, we compare the increase to the original food cost. $\newline$ Percentage Increase = $(\frac{\text{Increase}}{\text{Original Food Cost}}) \times 100$ $\newline$ Percentage Increase = $(\frac{(\$15.59 - \$11.99)}{\$4.31}) \times 100$
Correct Calculation: Calculate the percentage increase. $\newline$ Percentage Increase = $(\$3.60 / \$4.31) \times 100$
Correct Calculation: Calculate the percentage increase. $\newline$ Percentage Increase = $(\$3.60 / \$4.31) \times 100$ Perform the calculation to find the percentage increase. $\newline$ Percentage Increase = $0.83526 \times 100$ $\newline$ Percentage Increase = $83.526\%$ $\newline$ This doesn't seem right, we compared the increase to the food cost instead of the original price. Let's correct that.
