Question

Karla Shopping at Unido. Once a month, the state emails her coupons for 65% off her purchase. She ties $125 of merchandise in her shopping bag. While walking to the register, Karla finds another coupon for 30% off her purchase. Write and solve an equation that can be used to determine the amount Karla will spend on her items.

a) 0.65 * (125 - 0.3 * 125)

b) 125 - 0.65 * 125 - 0.3 * (125 - 0.65 * 125)

c) 125 - 0.65 * 125 + 0.3 * (125 - 0.65 * 125)

d) 0.65 * 125 + 0.3 * (125 - 0.65 * 125)

Answer 1

The equation that can be used to determine the amount Karla will spend on her items is 125 - 0.65 * 125 + 0.3 * (125 - 0.65 * 125). Karla will spend $56.88 on her items.

Step-by-step explanation:

To determine the amount Karla will spend on her items, we can use the equation 125 - 0.65 * 125 + 0.3 * (125 - 0.65 * 125), which is option c. Let's break it down step by step:

1. Multiply 0.65 by 125 to find the discount amount of the first coupon: 0.65 * 125 = 81.25 (rounded to 2 decimal places).
2. Subtract the discount from the original price to find the remaining price after the first coupon: 125 - 81.25 = 43.75 (rounded to 2 decimal places).
3. Multiply 0.3 by the difference calculated above to find the discount amount of the second coupon: 0.3 * 43.75 = 13.13 (rounded to 2 decimal places).
4. Add the second discount to the remaining price to find the final amount Karla will spend: 43.75 + 13.13 = 56.88 (rounded to 2 decimal places).

Therefore, Karla will spend $56.88 on her items.
