frozen [14]

Answer:

Brad picked 130 apples. Andy picked 45 apples. Krystal picked 115 apples.

Step-by-step explanation:

B = 2Y                A = Y - 20            K = Y + 50        B + A + K + Y = 355

130 = 2(65)        45 = 65 - 20        115 = 65 + 50     130 + 45 = 115 + 65 = 355

130 = 130           45 = 45                115 = 115

A pair of snow boots at an equipment store in Big Bear that originally cost $80 is on sale for $56. What is the rate of discount
8_murik_8 [283]

Divide the sale price by the original price:

56 / 89 = 0.7

Multiply by 100:

0.7 x 100 = 70%

The sale price is 70% of the original price, so the discount would be 30% (100-70= 30)
