Question

5 from unit 4, lesson 10 a shopper bought a watermelon, a pack of napkins, and some paper plates. in his state, there is no tax on food. the tax rate on non - food items is 5%. the total for the three items he bought was $8.25 before tax, and he paid $0.19 in tax. how much did the watermelon cost? 1. last year, scientists counted 12 foxes in a conservation area. this year, they counted 50% more than that. how many foxes did they count this year?

Explanation:

Step1: Find non - food cost before tax

Let the cost of non - food items (napkins and paper plates) before tax be $x$. The tax rate on non - food items is $5\%$ or $0.05$ in decimal. The tax paid on non - food items is $0.19$. We know that tax = tax rate×cost of non - food items before tax, so $0.05x = 0.19$. Solving for $x$, we get $x=\frac{0.19}{0.05}=3.8$.

Step2: Find watermelon cost

The total cost before tax for all three items is $8.25$. Let the cost of the watermelon be $y$. We know that $y + x=8.25$, and we found $x = 3.8$. So $y=8.25 - 3.8 = 4.45$.

Answer:

The watermelon cost $\$4.45$.
