Do 7 •2.50 and do 4•.50 Add those values together. Subtract that value from the $20. Then divide what you have left by .12

she has $20 she can use so the limit of money is 20. 7*2.50=17.5 and 4*.50=2 is she’d be using $19.50 she has 0.50 left so you would divide 0.50 by 0.12 which is 4.16 so she could get 4 pencils.
