Answer:

x = 12

Step-by-step explanation:

Equation: 0.52(x) + 0.72(4) = 0.57(x + 4)

0.52(x) + 0.72(4) = 0.57(x + 4) $\longmapsto$ Multiply

0.52x + 2.88 = 0.57x + 2.28 $\longmapsto$ Subtract 0.52x from both sides

2.88 = 0.05x + 2.28 $\longmapsto$ Subtract 2.28 from both sides

0.6 = 0.05x $\longmapsto$ Divide all sides by 0.05

x = 12

The sale price for a bicycle is $315 dollars. The original price was first discounted by 50% and then discounted an additional 1

Len [333]

This means that the bicycle was discounted in total by 60%, so $315 is 40% of the original price to get 40% to 100% youd multiply it by 2.5 so so the same to the price 315 x 2.5= 787.5
