Question

An arts teacher bought 20 art kits at $50 each and a number of other art kits costing $20 each. In all, he spent $1200. How many of the cheaper art kits did he buy.

Answer 1

Answer:

15

he bought that much for $1200

Answer 2

Answer:

10

Step-by-step explanation:

if 20 art kits = $50 for each and x art kits for $20 for each the total amount of expensive art kits is 1000 and so , 1000 + x = 1200 then 1200 -1000 = 200 so that means :-

$50 × 20 art kits = 1000

$20 × x art kits = 200

so 200 ÷20 =10

therefore he bought 10 cheaper art kits .
