Answer:
-22%
Step-by-step explanation:
The percent decrease can be found by subtracting the original amount from the sale price. Divide the result by the original price and multiplying the decimal by 100 for the percent.
670.80 - 860 = -189.2
-189.2/860 = -0.22
-0.22*100 = -22%
Answer:
$24.50
Step-by-step explanation:
60% of $50= $30
$50-$30= $20
15% of $20= $4.50
$20+$4.50= $24.50
200 - [ ( 50 - 4 ) × 3 + 5 ]
= 200 - [ 46 × 3 + 5 ]
<Put brackets around the 2 number that enclose the times sign as a reminder to do that first>
= 200 - [ ( 46 × 3 ) + 5 ]
= 200 - [ 138 + 5 ]
= 200 - (143)
= 57
Hope this helps!
