Jamal buys 15 pencils for $0.90 each and a notebook for $1.25. the cashier says the total is $32.25, but jamal believes there was a mistake.
which equation could he use to check the reasonableness of the total?
15 × 1 + 1 = 16
15 × (1 + 1) = 30
15 × 9 + 1 = 136
15 × (9 + 1) = 150

15 × 1 + 1 = 16

Step-by-step explanation:

15 pencils for $0.90 = 15*.90

1 notebook for 1.25 = 1*1.25

Add them together

15*.90+1*1.25

We can round .90 to 1 dollar an 1.25 to 1 dollar

15*1 + 1*1

15+1 =16
