Step-by-step explanation:
so, for me basically, as there are two food, I can do,.20$ ÷ 2= 10$
Then, I know that 10$ is the amount of money spent of each.
TACOS- EQ.1
t*$2.50= 10$
t=10$÷2.50=4
t=4
FRENCH FRIES-EQ.2
f*$1.25= 10$
f=10$÷$1.25= 8
f=8
NOW,
t*$2.50+ f*$1.25= $20
PUT EQUATION 1.
(4)*2.50+f*1.25=$20
PUT EQUATION 2
4*2.50+ 8*1.25= $20
I really hope this helps!!
