Answer:
- 45 large candles
- 53 small candles
Step-by-step explanation:
Let c represent the number of large candles Jane sold. Then 98-c is the number of small candles. Her revenue is ...
8c +5(98-c) = 625
3c + 490 = 625 . . . . . . eliminate parentheses, collect terms
3c = 135 . . . . . . . . . . . . subtract 490
c = 45 . . . . . . . . . . . . . . divide by 3
Jane sold 45 large candles and 98-45 = 53 small candles.
If he goes 45 miles EACH hour then to solve multiply 45 by 6
45 x 6 = 270 miles
It should be: c+7 = 2c-13
you need to set the equations equal to each other so if s= c+7 and s= 2c -13 substitute one value of s into the other equation to solve
