Answer:
$36.00
Step-by-step explanation:
$12.00 - the total cost of 4 of equally priced gloves
$12.00 : 4 = $3.00 - the cost of 1 glove
The cost per glove is increased by $1.00. Therefore new cost of 1 glove is
$3.00 + $1.00 = $4.00
The total cost of 9 of gloves at the new price:
9 × $4.00 = $36.00
