Question

sally pays $25 for two tubes of paint: a blue tube and a red tube. the blue tube cost $7 more than the red tube. how much did each tube cost ?

Answer 1

Step-by-step explanation:

let the price of red tube be x, then

x+7 =25

25=7+x

25-7=x

x=18

red tube will be equal to x so red tube is equal to 18

and blue tube that is 7more than red tube is equal to 25-18=7
