Question

Evan and Dorinda make bracelets for a craft fair. Evan makes 10 bracelets the first day and 8 bracelets each day after that. Dorinda makes 8 bracelets the first day and 8 bracelet each day after that. If they make bracelets for 6 days how many bracelets will they make in all?

Answer 1

98

Explanation:

As a function of the number of days (d), Evan makes ...

evan = 10 +8(d -1) = 8d +2

Similarly, the number Dorinda makes is ...

dorinda = 8d

The total they make in d days is ...

evan +dorinda = (8d +2) +(8d) = 16d +2

In 6 days, they make 16·6 +2 = 96 +2 = 98 . . . bracelets

They will make 98 bracelets in 6 days.

_____

Evan makes 50; Dorinda makes 48.
