Question

A pen costs $2.29. A calculator costs 3 times as much as the pen. How much do a pen and a calculator cost together

Answer 1

9.16

So basically they said the pen costs 2.29 and the calculator cost 3 times more so we can multiply it with 3 or we can add also,

Here is an easy way to add:

Suppose it's 2.30 and 2×3 makes 6 and 3+3+3 makes 9 add 0 means 90 substaract 3 87 which means 6.87

So calculator costs 6.89 and pen cost 2.29 and when we add them we can 9.16 so the answer is $9.16

Hope this helps u

Answer 2

2.29 * 3 = 6.87 // tells you price of calculator
6.87 + 2.29 = 9.16 // tells you total price

the answer is $9.16
