Answer:
A and B
Step-by-step explanation:
Hopefully this helps
138 x ? = 75
? = 75/138 = 0.544(3sf)
so about 54.35% (2dp) decrease
First you need to make a multiplier for 100-2.1%, to do this you minus the values and divide it by 100:
100-2.1 = 97.9
97.9/100 = 0.979
Then you multiply all the questions by it:
$45 * 0.979 = $44.055
$765 * 0.979 = $748.935
$1300 * 0.979 = $1272.7
Hope this helps! :)
