Question

Ruby has a monthly salary of $1,800 and also earns 6% commission on her sales. If Ruby had $37,000 in sales last month, what were her total earnings for the month?

a.$1,908
b.$2,220
c.$2,328
d.$4,020

Answer 1

6% of her $37,000 in sales: 37,000 x 0.06 = 2220

Salary $1,800 + $2,220 (commission) = $4,020

So her total earnings: $4,020

Answer 2

d. $4,020.

Explanation:

We have been given that Ruby has a monthly salary of $1,800 and also earns 6% commission on her sales. Ruby had $37,000 in sales last month.

Ruby total earning for the given month will be equal to 6% of the total sales plus monthly salary.

`\text{Ruby's total earnings for the month}=((6)/(100)* \$37,000)+\$1,800`

`\text{Ruby's total earnings for the month}=(6* \$370)+\$1,800`

`\text{Ruby's total earnings for the month}=\$2,220+\$1,800`

`\text{Ruby's total earnings for the month}=\$4,020`

Therefore, Ruby's total earnings for the given month were $4,020 and option 'd' is the correct choice.
