Question 388518
you are buying scarves and gloves as gifts. a scarf costs $2 less than each pair of gloves. gloves cost $7. you buy 12 items for $62. how many gloves did you buy ?
.
Since
g = pairs of gloves purchased
then
12-g = scarfs purchased
.
7g + 5(12-g) = 62
7g + 60-5g = 62
2g + 60 = 62
2g = 2
g = 1 (gloves purchased)
