Math problem

Question

Jen owns a small business that sells only two products. It takes Jen six and a half hours to make a knit scarf and ten hours to knit a pair of gloves. It took Jen 906 hours to knit a total of 120 scarves and gloves last year. How many scarves and gloves did she knit? If she sells scarves for $12 and gloves for $15,what was her sales revenue for the year?

Answer 1

6.5s +10g =906

s+g=120

6.5s +6.5g= 6.5(120)= 780

3.5g=906- 126

g= 126/3.5= 36 gloves

s=120-36= 84 scarfs

12(84)+15(36)= $1,548
