Answer:
B
Step-by-step explanation:
let X represent the smaller paintings and Y represent the larger paintings
since she bought 8 paintings
X+Y=8
She bought all the eight paintings for $230 and X is worth 25 while Y is worth 40
25×X+40×Y=230
25X+40Y=230
C because it’s the only one in between 60 and 260
So 70 miles per hour is 70 mile/1hour
1 mile=5280 feet
70 tmes 5280=feet=36,960
so 36,960 feet per hour
