hey! who wuvzzzzzzz money??? $$ meeee deb is saving $54 per month to buy a new camera. use the distributive property to mentally find how much she has saved after 7 months. explain.
basically
54 times 7
what's the answer
distributive says
a(b+c)=ab+ac
we can split 54 times 7 into
we know that 54=50+4
so we can do 7 times 54 as
7(50+4)=7(50)+7(4)=350+28=378
she saved $378 after 7 months
