Steve set up a business making friendship bracelets. He earned $70 in January. He is projected to earn 120% more in February. How much is Steve projected to make in February? $84 $98 $154 $190

Shadow:

Multiply 70 by 1.2

Shadow:

1.2 = 120%

Gucchi:

its 84

Gucchi:

right?

Gucchi:

i thought it was $154

Shadow:

Yeah by the phrasing of the question, I earn x% more means I add what I earned in the previous month, plus the x%. So 70 + 84

Gucchi:

Alright, thanks

Gucchi:

I searched this question up online and ppl say it is $84

Gucchi:

I'm confused by that

Shadow:

Think of it this way. Say I earned $10 on Monday. I earn 10% more on Tuesday. Which means I earned $11 on Tuesday, as I earned 10% more than what I did on Monday. And Monday I earned $10, and 10% of $10 is $1, so $10 + $1 = $1.

Gucchi:

Hmm, Yeah it makes more sense
